Some versions of the ledbar MCU have a reset pin. It needs to be
correctly initialized or we might keep the MCU in reset state.

cd0283788f mediatek: cast literal value to char
Or the comparison against a signed char is always true, because the
literal 0xaa is treated as an unsigned int, to which the signed char is
casted during comparison. 0xaa is above the positive values of a signed
char and negative signed char values result in values larger than 0xaa
when casted to unsigned int.

because we're dealing with a single char.

fd5ced246a mediatek: fix Ubiquiti UniFi 6 LR LED
When adding Kernel 5.10 support, the kernel configuration did not
include the LED driver required for the UniFi 6 LR. Also the actual
driver source went missing.

Fixes commit c46ccb69d17e ("mediatek: mt7622: add Linux 5.10 support")
