Subject: [PATCH 03/19] mach-u300: delete irq_to_gpio() function

From: Linus Walleij <linus.walleij@...aro.org>

This function is not used in the U300 build, and on the whole the
call is hard to consolidate so get rid of it from this machine.

Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
