Larisa Grigore d0f379279c spi: spi-fsl-lpspi: Clear status register after disabling the module 
[ Upstream commit dedf9c93de ]

Clear the error flags after disabling the module to avoid the case when
a flag is set again between flag clear and module disable. And use
SR_CLEAR_MASK to replace hardcoded value for improved readability.

Although fsl_lpspi_reset() was only introduced in commit a15dc3d657
("spi: lpspi: Fix CLK pin becomes low before one transfer"), the
original driver only reset SR in the interrupt handler, making it
vulnerable to the same issue. Therefore the fixes commit is set at the
introduction of the driver.

Fixes: 5314987de5 ("spi: imx: add lpspi bus driver")
