Disable legacy codepage handling in bootloaders
Turn off legacy codepage handling in the filesystem code for
bootloaders, and support ISO-8859-1 (Latin-1) only.
This only affects DOS 8.3 filename parsing when FAT32 long
names are unavailable; long names are Unicode and can always
be decoded properly regardless of this setting.
In reality, bootloaders never supported codepages other than
Latin-1 in the first place. They did contain the code to load
codepages from disk, but had no way to actually change the
codepage away from Latin-1.
Compiling out this useless codepage handling code frees up
precious space for very size-constrained bootloaders like the
Sansa e200v2.
