media: add ar0234 sensor driver
Add ar0234 camera sensor driver code, max96712 GMSL serializer code, mode tables and makefile changes. These drivers are copied from K5.10 camera driver repo. Changes include svcacv warning fix and eeprom read status is ignored due to bug 4064490. Bug 3583587 Bug 4064490 Change-Id: I7ea0ecf959caccafd283c8db5fb7c3be912cf8bb Signed-off-by: Ankur Pawar <ankurp@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/2868422 Reviewed-by: Laxman Dewangan <ldewangan@nvidia.com> GVS: Gerrit_Virtual_Submit <buildbot_gerritrpt@nvidia.com>
