Re: [U-Boot] rockchip: rk3288: Add support for drive-strength in PINCTRL

Currently, drive-strenght to 12ma are described and supposed to be used on RK3288. However, the pinctrl driver for this SoC only handles muxing and pull up/pull down via PU/PD control registers. So complex IPs like GMAC are working in normal ethernet 100mbps, but not at 1gbps typically.

This commit adds support for handling drive-strength of 12ma, when it's defined in the DT.
