[v7,0/5] Add support for the Hynix Hi-846 camera

hi,

patch 1, 2 and 3 add support for the SK Hynix Hi-846 CMOS images sensor.
It includes the dt-bindings and the driver.

Patches 4 and 5 are optional and don't have to hold patch 1-3 back:
if i2c-cardlist is deprecated, ignore it and act on it appropriately;
and the arm64 defconfig is just convenience for now.

best wishes,

                              martin
