soc/intel/common/gpio: support 16-bit CPU Port ID
- Add Kconfig: SOC_INTEL_COMMON_BLOCK_GPIO_16BIT_CPU_PORTID.
- Change cpu_port field to 16-bit width if the Kconfig is set.
BUG=none
TEST=boot to OS and use iotools to read the registers that use 16-bit
port ID such as IOM AUX Bias Ctrl register to verify the 16-bit group
ID field. The bit 15:8 of the returned port ID value should be 0xF2
instead of zero.
