dmaengine: sirf: enable the driver support new SiRFmarco SoC
The driver supports old up SiRFprimaII SoCs, this patch makes it support
the new SiRFmarco as well.
SiRFmarco, as a SMP SoC, adds new DMA_INT_EN_CLR and DMA_CH_LOOP_CTRL_CLR
registers, to disable IRQ/Channel, we should write 1 to the corresponding
bit in the two CLEAR register.
Tested on SiRFmarco using SPI driver:
$ /mnt/spidev-sirftest -D /dev/spidev32766.0
spi mode: 0
bits per word: 8
max speed: 500000 Hz (500 KHz)
