gpio: Add support for Intel Crystal Cove PMIC
Devices based on Intel SoC products such as Baytrail have a Power Management IC. In the PMIC there are subsystems for voltage regulation, A/D conversion, GPIO and PWMs. The PMIC in Baytrail-T platform is called Crystal Cove. This patch adds support for the GPIO function in Crystal Cove.
