media: camss: set VFE bpl_alignment to 16 for sdm845 and sm8250
[ Upstream commit d5b7eb477c286f6ceccbb38704136eea0e6b09ca ]
From the experiments with camera sensors using SGRBG10_1X10/3280x2464 and
SRGGB10_1X10/3280x2464 formats, it becomes clear that on sdm845 and sm8250
VFE outputs the lines padded to a length multiple of 16 bytes. As in the
current driver the value of the bpl_alignment is set to 8 bytes, the frames
captured in formats with the bytes-per-line value being not a multiple of
16 get corrupted.
Set the bpl_alignment of the camss video output device to 16 for sdm845 and
sm8250 to fix that.
