sh: sh7757: remove nonexistent GPIO_PT[JLNQ]7_RESV to fix pinctrl registration
Commit 3810e96056ff ("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 pinctrl registration failures, as seen on sh7722: sh-pfc pfc-sh7722: pin 0 already registered sh-pfc pfc-sh7722: error during pin registration sh-pfc pfc-sh7722: could not register: -22 sh-pfc: probe of pfc-sh7722 failed with error -22 Remove GPIO_PT[JLNQ]7_RESV from the enum to fix this.
