linux-postmarketos-qcom-milos 7.3.0: the kernel follows combined-stable onto v7.3.0-milos

The source branch moved to Luca Weiss's v7.3.0-milos tag (the carries that
mainline 7.3 absorbed are gone, the rest rebased, plus the in-flight QRTR
HELLO fix the modem needs at boot). The config is the 7.2 image config run
through olddefconfig on the new tree, with TOUCHSCREEN_ESWIN_EPH8621=y (the
upstream touchscreen driver replaces 7.2's unconditional downstream one;
without it the image has no touch) and HW_RANDOM_QCOM=y (CRYPTO_DEV_QCOM_RNG
moved to hw_random). QCE is marked BROKEN upstream and drops out, which
left the DT node crypto@1dfa000 without a driver: an interconnect consumer
that never probes kept the qnoc-milos providers from reaching sync_state
and every bus at its boot-time maximum vote, in sleep too; combined-stable
disables the node (c35fa276b496), which CI picks up with the tip.
ARM64_BTI_KERNEL is excluded for clang >= 21 by the base. The package
depends on soc-fairphone-fp6-audio >= 5: the 7.3 card name has its
topology and UCM only there, and booted with the version 4 files this
kernel has no sound card at all (the topology load fails, the card does
not instantiate). The 7.1-era
resolve_btfids patch goes: this config has DEBUG_INFO_REDUCED=y, so BTF is
off and the tool it fixes is never built (pmaports dropped it at 7.2.0 as
well). pmaports still ships 7.2.0 for this device.
