IRQ 0..7 are not supported by the driver for SPEAr320 SOC family.
IRQ 0 is not reserved in SPEAr320 SOC (assigned to GPIOINT).
Furthermore, in SPEAr320s SOC variant, IRQ 0..6 are assigned
as follow:
IRQ 6 - NGPIO_INTR: Combined status of edge programmable
interrupts from GPIO ports
IRQ 5 - TX_OR_INTR: I2S interrupt on Transmit FIFO overrun
IRQ 4 - TX_EMP_INTR: I2S interrupt on Transmit FIFO empty
IRQ 3 - RX_OR_INTR: I2S interrupt on Receive FIFO overrun
IRQ 2 - RX_DA_INTR: I2S interrupt on data available in Receive FIFO
IRQ 1 - Reserved
IRQ 0 - GPIO_INTR: Legacy interrupt from GPIO ports
Add support for these IRQs in SPEAr320 SOC family.

I took patches 4 and 6 into the soc tree now.
