ARM: SAMSUNG: Convert irq-vic-timer to irq_ functions
Conver the VIC timer interrupts to use the irq_ versions of the IRQ
operatiosn introduced in 2.6.37, storing the mask for the timer
interrupt in the chip_data of the irq_data in order to save having to
do a substraction and a shift on every operation.
