powerpc/5200: Rework GPT driver to also be an IRQ controller
This patch adds IRQ controller support to the MPC5200 General
Purpose Timer (GPT) device driver. With this patch the mpc5200-gpt
driver supports both GPIO and IRQ functions.
The GPT driver was contained within the mpc52xx_gpio.c file, but this
patch moves it out into a new file (mpc52xx_gpt.c) since it has more
than just GPIO functionality now and it was only grouped with the
mpc52xx-gpio drivers as a matter of convenience before. Also, this
driver will most likely get extended again to also provide support
for the timer function.
Implementation note: Alternately, I could have tried to implement
the IRQ support as a separate driver and left the GPIO portion alone.
However, multiple functions of this device (ie. GPIO input+interrupt
controller, or timer+GPIO) can be active at the same time and the
registers are shared so it is safer to contain all functionality
within a single driver.
