ARM: pxa: remove irq_to_gpio from ezx-pcap driver

Browse source 
The irq_to_gpio function was removed from the pxa platform
in linux-3.2, and this driver has been broken since.

There is actually no in-tree user of this driver that adds
this platform device, but the driver can and does get enabled
on some platforms.

Without this patch, building ezx_defconfig results in:

drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work':
drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]
