rockchip: rk3288: Revert MAC_TXCLK in pinctrl for GMAC

This reverts TXCLK toggling that was accidently dropped while reworking
commit 2454b719fb87 ("rockchip: rk3288: Add pinctrl support for the gmac
ethernet interface"). So the TX clock is enabled and we can use
GMAC_ROCKCHIP in 1Gbps when basic PINCTRL support is enabled
(!PINTRL_FULL).
