[PATCH v2 0/3] Implement GPIO cells for PALMAS and MAX77663 PMICs

[Svyatoslav Ryhel]

This patchset adds support for gpio-uclass to work with pmic gpio childrens
properly and implements MAX77663 and PALMAS GPIO cells/children as a 
reference and to be further used in devices I am currently maintaining.

All drivers are tested on actual hardware and confirmed to work as
expected. MAX77663 GPIO cell is tested on wexler qc750 tegra 3 device
and PALMAS GPIO cell is tested on tegra note 7 tegra 4 device.

Changes from v1:
 - isolate PMIC GPIO cells parsing behind enabling DM_PMIC
