meta-lxatac-bsp: linux-lxatac: upgrade to 6.7

[hnez]

umpf tag is now: 6.7/customers/lxa/lxatac/20231124-1. The tag includes the following topic branches:

• v6.7/customers/lxa/lxatac
• v6.7/topic/pwm-stm32
• v6.7/topic/pwm-backlight
• v6.7/topic/tty-trigger

No interesting changes this time around. The KSZ drive strength HACK got even HACKier because the #defines are no longer in scope, so I replaced them with the computed value.

Also right now the build fails because perf fails to compile. See the log log.do_compile.19484.txt for more information.

TODO before merging:

• [x] Add the drive-strength configuration to the devicetree. The drive strength configuration code does not quite work as intended yet, but that should change soon and then we can get rid of the HACK.
• [x] Fix the broken perf build. There is an oe-core commit that I copied from.
• [x] Wait for 6.7 to be released and update this PR to use the released tarball.

Closed in favor of #101, which does both the 6.5 -> 6.6 and the 6.6 -> 6.7 update.
