Just following the convention use in the rest of imx devices. See the
following comment at the top of the file:

/*
 * The naming convention for the pad modes is MX51_PAD_<padname>__<padmode>
 * If <padname> or <padmode> refers to a GPIO, it is named
 * GPIO_<unit>_<num> see also iomux-v3.h
 */

We could use the short names for pads being used in their "native mode".
But as soon as we use the pad in a different mode, such as
PAD_CSPI1_SCLK__GPIO_4_27 above, we'd need a different naming convention.

Regards,
Amit
