[PATCH V2 0/2] Fix WLED FSC Sync and brightness Sync settings

This patch series has the following two WLED fixes
1. As per the current implementation, for WLED5, after
the FSC (Full Scale Current) update the driver is incorrectly
toggling the MOD_SYNC register instead of toggling the SYNC register.
The patch 1/2 fixes this by toggling the SYNC register after
FSC update.

2. Currently, the sync bits are transitioned from 1 to 0
after FSC and brightness update. As per hardware team recommendation
the FSC and brightness sync takes place from 0 to 1 transition.
The patch 2/2 fies this issue.

Changes from V1:
1. Updated the cover letter.
2. Updated the description of the patches as per Daniel's suggestion.
