The VCC_PWRGD pin is used as an indication of VCC2 state and controls
the internal VCC_PWRGD signal. On Glower, the pin is floating so we
can't use it as is. Instead, configure the pin as a GPIO so that the
internal VCC_PWRGD is gated high.
Without this, nSIO_RESET would be kept asserted and most LPC-related

VESA DisplayPort Alt Mode on USB Type-C Standard specifies:
When DisplayPort Configuration is not selected (and the converter is
driving its HPD output low), the converter shall track the current
state of HPD, ready for appropriate indication when DisplayPort
Configuration is subsequently selected.
Not only are we violating specification here but it also causes a race
between enabling DPout muxes to AUX line which in turn causes GPU to
timeout trying to read EDID/DPCD on occasion.
Change adds post_config function for DFPs alternate mode and in the
case of DP it sets the dp_on flag there. This allows attention
function to correctly defer HPD_HI that may accompany 'DP status' VDM

Power up inhibit is intended to stop the AP from booting when the

IN_PCH_SLP_S5_DEASSERTED is already set by the time we get to S5 and we
