Arseniy Krasnov 43b70c9c4c mtd: rawnand: meson: invalidate cache on polling ECC bit
[ Upstream commit e732e39ed9 ]

'info_buf' memory is cached and driver polls ECC bit in it. This bit
is set by the NAND controller. If 'usleep_range()' returns before device
sets this bit, 'info_buf' will be cached and driver won't see update of
this bit and will loop forever.
