pinctrl: nomadik: Remove unused variable in nmk_gpio_dbg_show_one

Clang warns:

drivers/pinctrl/nomadik/pinctrl-nomadik.c:952:8: warning: unused
variable 'wake' [-Wunused-variable]
                bool wake;
                     ^
1 warning generated.

There were two wake declarations added to nmk_gpio_dbg_show_one when
converting it to use irq_has_action but only one is used within its
scope. Remove the unused one so there is no more warning.
