Commit 3810e96056ffddf6 ("sh: modify pinmux for SH7757 2nd cut") renamed
GPIO_PT[JLNQ]7 to GPIO_PT[JLNQ]7_RESV, and removed the existing users
from the pinmux_pins[] array.
However, pinmux_pins[] is initialized through PINMUX_GPIO(), using
designated array initializers, where the GPIO_* enums serve as indices.
Hence entries were not really removed, but replaced by (zero-filled)
holes. Such entries are treated as pin zero, which was registered
before, thus leading to initialization failures:
sh-pfc pfc-sh7757: pin 0 already registered
sh-pfc pfc-sh7757: error during pin registration
sh-pfc pfc-sh7757: could not register: -22
sh-pfc: probe of pfc-sh7757 failed with error -22
Remove GPIO_PT[JLNQ]7_RESV from the enum to fix this.

Untested due to lack of hardware and datasheet.
