configs/uevm5432_defconfig: bump Linux and U-Boot

- Bump Linux kernel to v6.8.10.
  The Devicetree has moved; update our config accordingly.

- Bump U-Boot to 2023.04.
  This is the most recent version we can use as U-Boot 2023.07 dropped
  support for the uevm.
  OpenSSL is now required for the build.
  The default boot method has changed; switch to booting with an extlinux
  configuration to overcome this.
