6d41da8b7e imx: kernel: add USB storage boot support
Enable BLK_DEV_SD and USB_STORAGE so that rootfs can be on a USB Mass
Storage device.

This adds 23KiB to the compressed kernel size

3d66f55161 kernel: improve handling of CONFIG_IO_URING
Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.

No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.

Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

ff06edd1f0 kernel: Activate CONFIG_GPIOLIB in generic configuration
All targets expect the malta target already activate the CONFIG_GPIOLIB
option. Move it to generic kernel configuration and also activate it for
malta.

f430600d73 imx: bundle correct SDMA firmware for i.MX 7 boards
Import sdma-imx7d.bin from linux-firmware repository at commit:
55edf5202154: ("imx: sdma: update firmware to v3.5/v4.5")

Cortex-A7 boards (i.MX 7 based) use different SDMA firmware than i.MX 6
boards - bundle the correct files in per-subtarget kernel options.

539e60539a generic: enable CRYPTO_LIB_BLAKE2S[_X86|_ARM]
This is now built-in, enable so it won't propagate on target configs.

a98ded6c5c kernel: move some symbols to generic config
This commit add some enabled symbols to generic config.
LTO is only supported by clang compiler and therefore should
be disabled in the generic config instead of duplicating this
symbol in each target. CONFIG_LTO_NONE do this job.

The second group of symbols is enabled by the options available
in the generic config and is therefore added here:
* CONFIG_AF_UNIX_OOB is selected by CONFIG_NET && CONFIG_UNIX,
* CONFIG_BINARY_PRINTF is selected by CONFIG_BPF_SYSCALL,
* CONFIG_NET_SOCK_MSG is selected by CONFIG_BPF_SYSCALL && CONFIG_NET.

The other symbols are disabled and should be in the generic config.

This commit also removes these symbols from subtargets.

bf1c3a5f3c imx: re-enable ARM arch timer
Config option `ARM_ARCH_TIMER` has been removed during rebasing onto
5.15 kernel in commit 2b395c2982 ("imx: update config for 5.15").

Anyway, as stated in commit 8cdc356f8c ("mediatek: mt7623: Re-enable
ARM arch timer") config option `ARM_ARCH_TIMER` cannot be enabled in the
config directly; it is only selected by `HAVE_ARM_ARCH_TIMER`. We need
to enable the latter in our config.
