This series has a few fixes for the Microchip ISC/XISC driver, found
while testing and from the feedback on the combined series [1].
Fixes only, sent ahead of the enhancements so they can reach stable.
The SBGGR10 and PM leak fixes are unchanged from [1] and keep their
Reviewed-by.
All but the two pfe_cfg0_bps cleanups carry a Fixes tag and Cc: stable.

Changes in v3:
- Rewrite the WB offset/gain register writes with FIELD_PREP() (Eugen). No
functional change; verified on SAMA7G5-EK.
- Collect Eugen's Reviewed-by on the PFE_CFG0 and macro-typo patches.
- Link to v2: https://lore.kernel.org/r/20260629-balki-isc-prefix-fixes-v1-v2-0-3b120cc3742f@microchip.com
Changes in v2:
- Squash the stop and start-error histogram/AWB-flush patches into one (Eugen).
- Store pfe_cfg0_bps unshifted, apply with FIELD_PREP() at the write (Eugen).
- Skip the WB register writes during the stop window too (isc->stop check).
- New patch: fix the ISC_PFG_CFG0_BPS macro name typo.
- Add Eugen's Reviewed-by on the IRQ-sync patch.
