soc/intel: Rename and move MISCCFG_GPIO_PM_CONFIG_BITS definition to soc/gpio.h

Lists of changes:
1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS
2. An advanced GPIO PM capabilities has been introduced in CNP PCH.

Refer to 'include/intelblock/gpio.h' for details.

Now with TGP PCH, additional bits are defined in the MISCCFG register
for GPIO PM control. This results in different SoCs supporting
different number of bits. The bits defined in earlier platforms
(CNL, CML, ICL) are present on TGL, JSL and ADL too. Hence, refactor the
common GPIO code to move MISCCFG bit definitions from intelblock/gpio.h
to soc/gpio.h so that each SoC can provide the definition of
MISCCFG_GPIO_PM_CONFIG_BITS as per the hardware support.

TEST=On ADL, TGL and JSL platform.
Without this CL :
GPIO COMM 0 MISCCFG:0xC0 (Bit 6 and 7 enable)

With this CL :
GPIO COMM 0 MISCCFG: 0x00 (Bit 6 and 7 disable)
