power/icelake: Add SLP_S5 as a watched power signal
Add SLP_S5_SIGNAL_L as a power signal we start observing and reporting
changes on for alderlake. Note that without
CONFIG_HOSTCMD_ESPI_VW_SLP_S5, no software actually responds to changes
on this line. Additionally, without the above config switched on,
SLP_S5_SIGNAL_L defaults to SLP_S4_SIGNAL_L, so we're actually watching
VW_SLP_S4 and reporting it as SLP_S5_DEASSERTED. There's nothing
technically wrong with this (since nobody takes any action now on the
new signal anyway). But to keep things comprehensible I'll add a
dependency on the change that flips on VW_SLP_S5 support, where we'll
actually start watching, reporting on, and responding to VW_SLP_S5
under its correct power signal name.
