sc8180x changes
- upgrade kernel to 6.6.0
- fix UFS with cmdline from thinkpad x13s
- add pmic glink modules to initramfs which seem to be required for USB now
- switch to systemd-boot
I'm doing everything in one MR, because switch to systemd-boot requires kernel config, and new kernel can't be booted without new initfs modules, so I want these things merged simultaneously
