linux-postmarketos-qcom-sdm670: upgrade to v6.11.3 + related changes

Thanks to Joel and Pan, support for the Pixel 3a rear camera was added. The IMX363 driver was originally made by Joel for the Pocophone F1 (SDM845) and added by Pan along with the nodes in the device tree.

Thanks to Robert Mader, resetting was added to the IMX355 startup sequence.

Thanks to Arnaud Ferarris, the chassis type property was added to the Pixel 3a device tree. This makes the information about the form factor available to userspace.

Support for q6voice audio calibration was added. This consists of a q6core patch to register topologies from the global ACDB and a q6voice patch to add an ALSA control. The known use case for this is calling newer phones over VoLTE.

The VoiceMMode1 support was re-added from msm8953-mainline. The new patch from Affe Null has no merge conflicts with the up-to-date q6voice patches in msm8916-mainline. This resulted in an authorship change.

The Tianma panel for the Pixel 3a XL was added along with its corresponding device tree, due to confirmation that this panel is in production devices.

The camera subsystem patches were sent upstream and their review comments were applied.

The sdm845-mainline patches were re-picked from the new sdm845-6.11_rc2 release. Some GPU patches were re-picked from linux-next because they were applied.

Bluetooth, USB, I2C, eMMC, modem, video acceleration, WiFi, haptics, NFC, sensors, touchscreen, and thermals should work and be slightly broken like before.
