This patch series contains 2 fixes to the imx_spi_flush_txfifo function.

The first fix prevents a case in which calling imx_spi_flush_txfifo while the 
controller is configured (by the guest driver) to use a burst length that isn't 
a multiple of 8 will cause an infinite loop.

The second fix makes the spi controller compatible with slaves + guest drivers
that expect to make transaction larger than 8 bits by removing an unnecessary 
cast.

This patch series was tested by running `make check` and by booting linux on
a sabrelite machine (which uses an spi flash)

Applied to target-arm.next, thanks.
