[U-Boot] [PATCH v6 5/6] pinctrl: mxs: Add support for i.MX2[38] mxs pinctrl driver

The code responsible for setting proper values in the MUX registers (in the mxs_pinctrl_set_state()) has been ported from Linux kernel - SHA1: 17bb763e7eaf tag v5.1.11 from linux-stable. As the pinctrl node in the imx28.dtsi file has gpio pins nodes as subnodes, it was necessary to use 'dm_scan_fd
