media: qcom: camss: Use proper BPL alignment helper and non-power-of-two rounding

Bytes-per-line (BPL) alignment in CAMSS currently uses ALIGN(), which
only works correctly for power-of-two values. Some RAW Bayer packing
formats (e.g. RAW10/12/14) require non-power-of-two alignment such as
3, 5, or 7-byte multiples, so ALIGN() produces incorrect results.

Introduce the use of roundup() with the per-format alignment returned by
camss_format_get_bpl_alignment() when no hardware alignment is enforced
(video->bpl_alignment).
