This patch ensures to be able to drive SYS_SLP_S0IX_L `low` based
on the state of the system while `SLP_S0_L` signal is `low` (while
the system is in S0ix).
Implemented runtime ASL method (MS0X) being called by PEPD device
_DSM to configure `SLP_S0_GATE (GPP_H14)` PIN at S0ix entry/exit.
Scope (\_SB)
{
Method (MS0X, 1, Serialized)
{
If ((Arg0 == One))
{
\_SB.PCI0.CTXS (0x75)
}
Else
{
\_SB.PCI0.STXS (0x75)
}
}
BUG=b:256807255
TEST=Able to see SYS_SLP_S0IX_L goes low in S0ix.
