ARM: shmobile: armadillo800eva: Don't request GPIO 166 in board code

3c516c521037416b3a3d3c140fac3f837415a3ea
(ARM: shmobile: armadillo800eva: Register pinctrl mapping for INTC)
mistakenly requests GPIO 166 in board code,
most probably due to a wrong merge conflict resolution.
As the GPIO is passed to the st1232 driver through platform
data and requested by the driver,
there's no need to request it in board code. Fix it.
