rockchip: pinctrl: rk3399: add GMAC (RGMII only) support
To add GMAC (Gigabit Ethernet) support (limited to RGMII only at this
point), we need support for additional pin-configuration. This commit
adds the pinctrl support for GMAC in RGMII signalling mode:
* adds a PERIPH_ID_GMAC and the mapping from IRQ number to PERIPH_ID
* adds the required defines (in the GRF support) for configuring the
GPIOC pins for RGMII
* configures the RGMII pins (in GPIOC) when requested via pinctrl
