[PATCH 15/18] media: microchip-isc: decouple histogram cycling from AWB mode

[Balamanikandan Gunasundar]

From: Balakrishnan Sambath <balakrishnan.s at microchip.com>

Fix histogram cycling stopping after first channel when AWB is disabled.
Now the histogram cycling will continue even when AWB is disabled,
enabling hardware histogram data export to userspace.
