2018-12-10soc/intel/cannonlake: Fix GPIO reportingDuncan Laurie
The kernel GPIO driver only expects some GPIO communities to be exported in the _CRS and it will not work correctly if the other communities are exported. CNL-LP: GPIO communities 0, 1, 4 CNL-H: GPIO communities 0, 1, 3, 4 Additionally one of the pin offset values was incorrect in GPIO community 1 for CNL-LP. This doesn't have any specific failure mode but it was found when auditing the GPIO code. Details of the kernel expected map can be found in the linux kernel at drivers/pinctrl/intel/pinctrl-cannonlake.c BUG=b:120686247 TEST=check /sys/kernel/debug/pinctrl/INT34BB:00/pins to ensure that pins >= 198 are not reading all zeros for the pin config registers.

2018-02-16soc/intel/cannonlake: Update GPIO ASLLijian Zhao
GPIO pin definition had been updated to match Cannonlake PCH-LP EDS, hence the ACPI dsdt table will include those changes as well. BUG=None TEST=Build coreboot image, flah coreboot image into DUT, and target system can boot up into OS.
