intel-ucode: restore working firmware blob 06-55-04 to avoid reboot bug
Firmware blob 06-55-04 in intel-ucode versions > 20190918 causes lockups when warm-rebooting certain Xeon and HEDT CPUs. ([Upstream issue](https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/21)) This PR replaces the affected blob with the last known good version.

A patch file from https://github.com/void-linux/void-packages/pull/18412.patch is attached
