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.

+Subject: [PATCH 1/2] libcamera: simple: Enable softISP for the Pinephone
+
+In theory the PP should be able to use the actual HW ISP, however in
+practice this does not work well yet - especially as the driver for the
+front camera in Megi differs heavily from the upstream one.
+
+Thus enable the swISP to make both cameras work reliably for now. This
+is essentially what Megapixels does as well. If the HW ISP situation
+improves, this can be dropped again.
