just wanted to make sure every mode has it's own pinctrl group so that it's
easy to review. Initially we were thinking something like
mmc1_pins_default_sdr12_sdr25.

But if you'd prefer we just use mmc1_pins_default for all modes that uses
default pinmux configuration, I can change it that way too.

Thanks
