extcon: intel-cht-wc: Use new cht_wc_model intel_soc_pmic field

The CHT_WC_VBUS_GPIO_CTLO GPIO actually driving an external 5V Vboost
converter for Vbus depends on the board on which the Cherry Trail -
Whiskey Cove PMIC is actually used.

Since the information about the exact PMIC setup is necessary in other
places too, struct intel_soc_pmic now has a new cht_wc_model field
indicating the board model.

Only poke the CHT_WC_VBUS_GPIO_CTLO GPIO if this new field is set to
INTEL_CHT_WC_GPD_WIN_POCKET, which indicates the Type-C (with PD and
DP-altmode) setup used on the GPD pocket and GPD win; and on which
this GPIO actually controls an external 5V Vboost converter.
