[PATCH] ARM:mfd: fix ezx-pcap build failure

[mark.asselstine@windriver.com (Mark Asselstine)]

Attempting to build the ezx_defconfig we get a build failure:

drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work':
drivers/mfd/ezx-pcap.c:205: error: implicit declaration of function 'irq_to_gpio'

Looking at this failure we can find that commit 4929f5a8a99f
[ARM:pxa: rename gpio_to_irq and irq_to_gpio] renamed irq_to_gpio()
to pxa_irq_to_gpio() but this change was not made in the ezx-pcap
driver.
