Shinya Kuribayashi 29fb08c300 i2c: i2c-sh_mobile: fix spurious transfer request timed out 
Ensure that any of preceding register write operations to the I2C
hardware block reached the module, and the write data is reflected
in the registers, before leaving the interrupt handler.

Otherwise, we'll suffer from spurious WAIT interrupts that lead to
'Transfer request timed out' message, and the transaction failed.
