Update dell 3050 patch to patch 15 (pwm fix)

Use patchset 15 instead of 14:
config/coreboot/default/patches/0061-WIP-OptiPlex-3050-Micro-port.patch

Rebase the verb patch; patchset 15 modified the Makefile:
config/coreboot/default/patches/0064-dell-optiplex_3050-add-hda_verb.c.patch

We were using patchset 14 for the 3050 micro:
https://review.coreboot.org/c/coreboot/+/82053/14

Now we use patchset 15:
https://review.coreboot.org/c/coreboot/+/82053/15

Without this patch, the fans are always on a low setting, on
the Dell OptiPlex 3050 Micro, even under stress conditions. With
this patch, the fans change speed according to CPU temperature.

I had to rebase my verb patch, because Mate modified the Makefile
to add his sch5555 handler, on the same line where I add hda_verb.

Mate tells me he will merge my verb and vbt patches into a further
patchset later on. For now, I've simply rebased these patches on
top of Mate's newer work; I've told him he can use them in his port.

I'm probably going to now issue a new revision ROM image for
Libreboot 20241008, so that users can get this fix sooner.
