camera: enable the FP6 ultra-wide pipeline (kernel config + patched libcamera)

Kernel config: CONFIG_VIDEO_OV13B10=m + CONFIG_VIDEO_DW9714=m — the camss
core, CAMCC and CCI were already enabled; the sensor and VCM drivers were
the only missing pieces. The camera carries themselves land via
milos-linux combined-stable (merge of the 'camera' topic branch,
nondescriptpointer's 5 patches, authorship preserved).

libcamera: new temp/ aport overriding pmOS 99990.7.2-r1 with -r2, adding
nondescriptpointer's OV13B10 sensor helper (gain = code/128, enables the
software-ISP AGC/AWB) and sensor properties patches on top of the pmOS
0.7.2 APKBUILD. Patch sha512s re-recorded from the actual files (his
APKBUILD diff carried stale hashes); all four patches verified to apply
against the v0.7.2 tarball.
