pwrctl: Add latch output to power control On the Zaius machine, the BMC signals that power up the CPU are gated by a latch to protect against GPIO blips during BMC reset/power loss. This adds an optional power GPIO configuration that controls the latch's enable pin. Its behavior is to assert high when the op-pwrctl runs, allowing power_up lines to propagate past their latches.
