As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

1. Create "rootfs_data" dynamicaly
U-Boot firmware images can contain only 2 UBI volumes: bootfs (container
with U-Boot + kernel + DTBs) and rootfs (e.g. squashfs). There is no way
to include "rootfs_data" UBI volume or make firmware file tell U-Boot to
create one.
For that reason "rootfs_data" needs to be created dynamically. Use
preinit script to handle that. Fire it right before "mount_root" one.
2. Relate "rootfs_data" to flashed firmware
As already explained flashing new firmware with U-Boot will do nothing
to the "rootfs_data". It could result in new firmware reusing old
"rootfs_data" overlay UBI volume and its file. Users expect a clean
state after flashing firmware (even if flashing the same one).
Solve that by reading flash counter of running firmware and storing it
in "rootfs_data" UBI volume. Every mismatch will result in wiping old
data.

the generic config since c7182123b9 ("kernel: make cryptoapi support
needed by mac80211 built-in"). So move the above options from the target
configs to the generic config to make it clear why do we need them.

BCM4908 devices with U-Boot use pkgtb firmware format. It's based on
U-Boot's FIT: DTB with configurations, images & embedded data.
This format contains bootfs, rootfs and optionally a first stage U-Boot
loader. Contained images need to be extracted & flashed.
Broadcom used two sets of firmwares: main & backup. It uses UBI volumes
"metadata1" & "metadata2" for storing U-Boot env variables with info
about flashed images.

This results in setting format specific data (format info, extract
commands) in a single function. It should help maintaining sysupgrade
code.
This change has been tested on Asus GT-AC5300 and Netgear R8000P.

This target does not activate CONFIG_PCI kernel configuration option, do
not activate the PCI feature. This will deactivate some PCI drivers
which are not building without PCI support in the kernel.
If PCI_SUPPORT or PCIE_SUPPORT are activated in the kernel configuration
the feature flag will be automatically set by the build system again.

Deactivate all the symbols of the B53 DSA driver in the generic kernel
configuration. Multiple targets are now using this drivers and they
only need some of the options.
This fixes the bcm4908 build which didn't deactivate all of the options.

New BCM4908 family based routers will use U-Boot bootloader. That will
require using a totally different firmware format. Kernel has to be put
in a FIT image.
OpenWrt has some helpers for generating .its files but they don't fit
BCM4908 requirements and there is no simple way of extending any of
them. The best solution seems to be storing an .its template.
BCM4908 bootfs may:
1. contain extra binaries (other than kernel & DTB)
2. include multiple DTB files
3. store device specific U-Boot configurations with custom properties
Such setups are too complex to generate using shell script. Raw .its
file on the other hand seems quire clean & reasonable.

CONFIG_COMPAT_32BIT_TIME is a new symbol and has to be set to avoid:
Provide system calls for 32-bit time_t (COMPAT_32BIT_TIME) [N/y/?] (NEW)
CONFIG_RELOCATABLE needs to be enabled to make kernel start booting.
That raises a question: do we really need CONFIG_EXPERT=y ?

In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.

Some targets select HZ=100, others HZ=250. There's no reason to select a higher

This enables building BCM4908 "raw" image that can be flashed using
bootloader web UI. It requires serial console access & stopping booting
by the "Press any key to stop auto run".
It's easy to build vendor like CHK image but it can't be safely flashed
using vendor UI at this point. Netgear implements method called "NAND
incremental flashing" that doesn't seem to flash bootfs partition as
provided.
Above method seems to update vmlinux.lz without updating 94908.dtb. It
prevents OpenWrt kernel from booting due to incomplete DTB file. Full
Netgear R8000P support can be enabled after finding a way to make vendor
firmware flash OpenWrt firmware including the 94908.dtb update.
