I'm fine with MX51_PAD_CSPI1_SCLK__GPIO_4_27, but I don't care for
MX51_PAD_GPIO_1_9__GPIO_1_9. How about changing the comment to

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