Lists of changes:
1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS
2. Move MISCCFG_GPIO_PM_CONFIG_BITS definition from intelblock/gpio.h to
soc/gpio.h. Refer to detailed description below to understand the
motivation behind this change.
An advanced GPIO PM capabilities has been introduced since CNP PCH,
refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions.
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 keep the bit definitions in intelblock/gpio.h, but
the definition of MISCCFG_GPIO_PM_CONFIG_BITS is moved to soc/gpio.h so
that each SoC can provide this as per 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)
