add milk-v megrez support. i've added a machine configuration, a kernel recipe u…sing the rockos upstream (which i believe is the same as the provided debian image from milk-v), and a wks file for an sd card image. with this i'm able to boot into core-image-minimal from an sd card: ``` Poky (Yocto Project Reference Distro) 5.0.7 milkv-megrez /dev/ttyS0 milkv-megrez login: root WARNING: Poky is a reference Yocto Project distribution that should be used for testing and development purposes only. It is recommended that you create your own distribution for production use. root@milkv-megrez:~# uname -a Linux milkv-megrez 6.6.73-yocto-standard-milkv-megrez #1 SMP Sun Jan 26 03:00:50 UTC 2025 riscv64 GNU/Linux root@milkv-megrez:~# ``` i did not figure out how to lay out the dtb in the boot partition correctly. `fdtfile` that came on the stock board is `eswin/eic7700-milkv-megrez.dtb` but i have to set it to `eic7700-milkv-megrez.dtb` because of how the wic tooling lays out dtbs in the boot partition and ftddir in extlinux.conf. feedback welcome, i would love to get this merged so others can use this :-)
