So far we have imx_gpio_mode() to configure a pinmux entry for the older
i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called
beforehand to configure the base address. Simplify this by introducing
SoC specific variants of imx_gpio_mode() which also pass the base
address. This makes initialization of the base address unnecessary and
the functions usable for PBL. Consequently also compile the code for
PBL.
