GPIOs are divided into different communities. Each community
consists of one or more GPIO groups. We need to configure the
groups in coreboot so that they are mapped properly.
GPIO comuinities in coreboot should match with the kernel gpio
communities also. Kernel reads the ASL file from coreboot. This
patch adds the proper community mapping in ASL code to match with
kernel code. In gpio_soc_defs.c file we are indexing the groups
correctly. In gpio.h file we define all the gpio devices as kernel
populates sysfs with separate gpio device for each community. This
patch is created based on Intel Tiger Lake Processor PCH Datasheet
with Document number:575857 and Chapter number:27.
BUG=b:144680462
BRANCH=none
TEST=Build and boot tigerlake rvp board. In /sys/kernel/debug/pinctrl
verify INTC34C5:0<1-3> listing all the pins for each community.
e.g., #cat /sys/kernel/debug/pinctrl/INT34C5:00/pins should list
all the community 0 pins.

GPIOs are divided into different communities. Each community
consists of one or more GPIO groups. We need to configure the
groups from coreboot so that they are mapped properly.
GPIO communities should be properly configured in GPIO_CFG and
MISCCFG registers. GPP_* defines in gpio_soc_defs.h are configured
in GPIO_CFG register while the PMC_GPP_* in pmc.h are used to
configure the MISCCFG registers.

BRANCH=none
TEST=Build and boot tigerlake rvp board. Verified that after
setting the gpe from devicetree the GPP_EN register for
that community gets updated setting that specific bit.
From the iotools i checked that GPE_EN register for that
community is updated with that specific bit set to 1.
