[PATCH] spi: spi-ti-qspi: clear wlen field while setting word length.

[Prahlad V <prahlad.eee@gmail.com>]

When a word length of 1 byte is selected and writing data of length
more than QSPI_WLEN_MAX_BYTES, first MAX_BYTES will be transfered
and remaining will be transfered byte by byte. In that case wlen
field should be cleared before setting.
