soc/intel/skylake: Implement GPIO ACPI AML generating functions

Implement GPIO ACPI AML generating functions that can be called by
coreboot drivers to generate GPIO manipulation code in AML. Following
API functions are implemented:

1. acpigen_soc_read_rx_gpio
2. acpigen_soc_get_tx_gpio
3. acpigen_soc_set_tx_gpio
4. acpigen_soc_clear_tx_gpio

In addition to the API functions above, helper functions are added to
gpio.asl to set/clear/get Tx value of GPIO.

BUG=b:62028489
