The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.
This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.
Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

These options doesn't show up unless some kernel packages are selected,
so they are not covered by kernel_menuconfig.
Manually add them so that a build with all kmods can pass without user
interaction.

This patch adds a new spi-nand driver which implements the SNFI of mt7622
and mt7629.
Unlike the existing snfi driver which makes use of the spi-mem framework
and the spi-nand framework with modified ecc support, this driver is
implemented directly on the mtd framework with other components untouched,
and provides better performance, and behaves exactly the same as the nand
framework.

The patch fixes the fifo rx mode for the mt7623. It is already accepted
upstream for Linux Kernel 5.15.
To test the spi we can change the dts file to
&spi0 {
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins_a>;
status = "okay";
spidev: spidev@0 {
compatible = "linux,spidev";
spi-max-frequency = <1000000>;
reg = <0>;
};
};
Afterwards we should see a spidev device under /dev/.
To test it we can further use spidev-test.

The image generation code for the U7623 board expects ext4 filesystem
to be selected in menuconfig and CONFIG_TARGET_ROOTFS_PARTSIZE to be
defined. Now that ext4 isn't enabled any more, the variable was missing

Set the default (104) instead of using the config variable to fix that.
