ramdisk+AnyKernel2: Remove workarounds from Unified f2fs/ext4 support
- Add working static+stripped busybox 1.22.1 (thanks @jimsth!)
- Remove workaround/hack required for older busybox binaries
- revert to busybox fstrim for suspend_trim now that it's back
ramdisk+AnyKernel2: synapse: fix pseudocolumns for live freq/volt
- lower frequencies or voltages would cause a misalignment, add a
dynamic spacer based on the voltage length to correct for it
