[PATCH/RFC 6/6] arm: shmobile: rcar-gen2: Remove unused rcar_gen2_read_mode_pins()

[PATCH/RFC 6/6] arm: shmobile: rcar-gen2: Remove unused rcar_gen2_read_mode_pins()

[Simon Horman]

The new boot mode reg infrastructure is now used in
place of rcar_gen2_read_mode_pins so the latter may now be removed.
