soc/intel/skl: set PEG port state to auto

Setting PegXEnable to 1, statically enables the PEG ports, which blocks
the SoC from going to deeper PC states. Instead, set the state to "auto"
(2), so the port gets disabled, when no device was detected.

Test: powertop on X11SSM-F shows SoC in PC8 like on vendor firmware
instead of just PC3.
