mb/google/brya: Implement SLP_S0_GATE signal
The SLP_S0_GATE# signal is used in conjunction with the PCH's SLP_S0# to
provide an indication to the rest of the platform when the system is
entering its software-initiated low-power state (i.e. S0ix). This lets
the platform distinguish between opportunistic S0ix entry and the runtime
suspend mechanism.
