[PATCH linux dev-5.10 16/35] ARM: dts: aspeed: tacoma: Remove CFAM reset GPIO

witherspoon hardware and p9 chips have very sensitive requirements for
the cfam-reset. We're seeing power faults with the kernel based cfam
reset due to this.

Could adapt the power application to use the new kernel based cfam reset
interface but there's not a lot to be gained there since the power
application is going away with p10 and this limitation is not present in
p10.
