spi: tegra114: clear packed bit for unpacked mode

BugLink: https://bugs.launchpad.net/bugs/1864773

[ Upstream commit 7b3d10cd ]

Fixes: Clear packed bit when not using packed mode.

Packed bit is not cleared when not using packed mode. This results
in transfer timeouts for the unpacked mode transfers followed by the
packed mode transfers.
