ARM: OMAP: dma: Clear status registers on enable/disable irq

Use omap_disable_channel_irq() function instead of directly accessing CICR
register in various functions.

The omap_disable_chanel_irq() function now clears pending interrupts
and disables interrupt on channel.

Functions omap2_enable_irq_lch()/omap2_disable_irq_lch() clear interrupt
status register.
