H A Dam300epd.cdiff 29ffa48fa64fcdfc71d80593c8ae79248bc27677 Tue Feb 04 13:30:05 CET 2014 Linus Walleij <linus.walleij@linaro.org> ARM: pxa: fix compilation problem on AM300EPD board

This board fails compilation like this:
arch/arm/mach-pxa/am300epd.c: In function ‘am300_cleanup’:
arch/arm/mach-pxa/am300epd.c:179:2: error: implicit declaration
of function ‘PXA_GPIO_TO_IRQ’ [-Werror=implicit-function-declaration]
free_irq(PXA_GPIO_TO_IRQ(RDY_GPIO_PIN), par);

This was caused by commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header"

This is because it was previously getting the macro PXA_GPIO_TO_IRQ
implicitly from <linux/gpio.h> which in turn implicitly included
<mach/gpio.h> which in turn included <mach/irqs.h>.

Add the missing include so that the board compiles again.
