ctly only because the return
value of {Read|Write}I2C is not checked in the driver.

Fix wait_ibsyclr by actually reading the IIC_CSR2 register to get the
updated status.  While here, change the return type to be an actual
errno instead of the private TRUE/FALSE define and remove the now
obvious comments about the return value.

Also, remove the local variable 'writestat' in WriteI2C and just
return the result of wait_ibsyclr.
