I2C: OMAP: Fix the interrupt clearing in OMAP4

Browse source

On OMAP4 we were writing 1 to IRQENABLE_CLR which cleared only
the arbitration lost interrupt. The patch intends to fix the same by writing 0
to the IE register clearing all interrupts.

This is based on the work done by Vikram Pandita <vikram.pandita@ti.com>.

The  changes from the original patch ...
-  Does not use the IRQENABLE_CLR register to clear as it is not mentioned
  to be legacy register IRQENABLE_CLR helps in  atomically
  setting/clearing specific interrupts, instead use the OMAP_I2C_IE_REG as we
  are clearing all interrupts.
