Wolfram Sang 1e1aace4a3 i2c: rcar: faster irq code to minimize HW race condition
[ Upstream commit c7b514ec97 ]

To avoid the HW race condition on R-Car Gen2 and earlier, we need to
write to ICMCR as soon as possible in the interrupt handler. We can
improve this by writing a static value instead of masking out bits.
