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.
