i2c: imx: Use correct function to write to register
commit 6c782a5ea56a799658e213a78dc1455264938afa upstream.
The i2c-imx driver incorrectly uses readb()/writeb() to read and
write to the appropriate registers when performing a repeated start.
The appropriate imx_i2c_read_reg()/imx_i2c_write_reg() functions
should be used instead. Performing a repeated start results in
a kernel panic. The platform is imx.
