be3fcd72e9 kernel: Deactivate B53 symbols in generic configuration
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.

505b7a2d08 kernel: move two symbols to the generic kconfigs

to the generic kconfigs. And resort the generic kconfigs while at it.

3326b5e75c treewide: switch the timer frequency to 100 Hz
Some targets select HZ=100, others HZ=250. There's no reason to select a higher
timer frequency (and 100 Hz are available in every architecture), so change all
targets to 100 Hz.

20b4f77bb6 kernel: add parser finding rootfs after CFE bootfs
It's required for BCM4908. It cannot use "bcm-wfi-fw" parser because
that one requires *two* JFFS2 partitions which is untested / unsupported
on the BCM4908 architecture. With a single JFFS2 partition "bcm-wfi-fw"
parser will:
1. Fail to find "vmlinux.lz" as it doesn't follow "1-openwrt" file
2. Create partitions that don't precisely match bootfs layout

The new parser is described in details in the MTD_SPLIT_CFE_BOOTFS
symbol help message.

c578fdfc29 bcm4908: initial work on the Broadcom BCM4908 target
BCM4906, BCM4908 and BCM49408 are SoCs with 64 bit ARMv8 B53 CPUs.
Upstream Linux is slowly getting support for that SoCs family so it
makes sense to add target for it.

This prepares initial support for:

1. Asus GT-AC5300
BCM4908 based device (4 CPUs) with 1024 MiB RAM, NAND, 8 LAN ports.

2. Netgear R8000P
BCM4906 based device (2 CPUs) with 512 MiB RAM, NAND, 4 LAN ports.

Flashing info will come later as we learn how to generate proper images.

It isn't usable yet (it only produces a bootable kernel) so "source-only"
is used.
