Hi,

efivarfs: rework the filesystem to make it human readable

today we use <varname>-<guid as %pUl>

such as Boot0000-8be4df61-93ca-11d2-aa0d-00e098032b8c

now we will use a different approach where will represent first the vendor
as a directory and then inside the associates variable.

But also create symlink on the vendor with readable name.

so it will look like this:

barebox@barebox EFI payload:/ ls -l /efivars/
