Subject: [PATCH] media: v4l2-fwnode: Fix setting V4L2_MBUS_DATA_ACTIVE_HIGH/LOW flag

From: Ondrej Jirman <megous@...ous.com>

When parallel bus is used and data-active is being parsed, incorrect
flags are cleared.

Clear the correct flag bits.

Fixes: e9be1b863e2c2948deb003df8edd9635b4611a8a (media: v4l: fwnode:
Use default parallel flags).
