ipq806x: i2c: write function fixed to avoid spurious success
The qup_i2c_write_fifo() made to query QUP_I2C_MASTER_STATUS after QUP
transitions into PAUSE state to ensure that it captures the correct status.
Handled more error bits.
BRANCH=chromeos-2013.04
BUG=chrome-os-partner:35328
TEST=Booted up storm P0.2, verified that the TPM on GSBI1 works.
Verified that SUCCESS is not reported when the write FIFO has failed.
