feat(linux): Fix am62l supported boot modes

Device am62lx does not currently support UHS modes due
to missing bench characterization numbers missing. Document
this in MMC-SD. This shall be updated later once we have added
UHS support for am62lx.

While we are here, fix the order of hs modes displayed to
match the table for eMMC.
