Closes #70.

Bumps the meta-mchp pin to the p64h-v2.3.0 tag: kernel 6.18.35 (PREEMPT_RT) and newer U-Boot, both from public repos over HTTP.

The 2.3.0 layer also recommends out-of-tree modules built from the private pic64-hpsc-hx/p64h-linux-examples repo over SSH (gpio/wdt as essential recommends, so even core-image-minimal would need org access). kas/machine/pic64hpsc.yml removes them so the build stays credential-free; the guide says how to re-enable them.

Tested with git-over-SSH disabled: core-image-minimal builds (only linux-mchp-p64h and u-boot-mchp remain from meta-mchp in the task graph) and boots to login on the P64H 2.3.0 QEMU model, 8 CPUs, no failed systemd units.

Moves the PIC64-HPSC machine to Microchip's 2.3.0 layer release:
kernel 6.12.22 -> 6.18.35 (PREEMPT_RT) and a newer U-Boot, both
fetched over HTTP from public repositories.

The 2.3.0 layer also recommends out-of-tree kernel modules built from
the private pic64-hpsc-hx/p64h-linux-examples repository (gpio and wdt
as essential recommends, so even core-image-minimal would need SSH
access to that organization). Remove them in kas/machine/pic64hpsc.yml
so the build stays credential-free, and say so in the guide.

Tested: with git-over-SSH disabled, core-image-minimal builds (only
linux-mchp-p64h and u-boot-mchp remain from meta-mchp) and boots to
login on the P64H 2.3.0 QEMU model with no failed systemd units.

Closes space-grade-linux#70

with the excluded private repos from Microchip the CI is now green.

the previous run with full meta-mchp packages did indeed fail as some Microchip repos are private in new release: https://github.com/space-grade-linux/meta-sgl/actions/runs/40087308202/job/120852761209
