core/linux-raspberrypi4 to 5.10.0.rc5-9

Align both config and config8 a bit more with rpi recommended config (make bcm2711_defconf).

Preemption model to desktop
Disable multi-core and SMT schedulers, see: raspberrypi/linux#1221
Set max CPU to 4
Set tick rate to 100 Hz for both kernels (although arm64 defaults to 250)
Add some CEC drivers as modules
Remove weak crypto modules ARC4 and Blowfish
