Trivial FATFS cleanup
Squashed commit of the following:
fs/fat/fs_fat32util.c: Most costmetic naming MBR to FBR in numerous locations. Change some ferr macros to fwarn. Use FBR macros insteac of MBR macros.
Add definitions for the FAT boot record (FBR).
fs/fat: Clean up some name BS_ and MBR_ refer to the same record and should use the same naming (MBR_).
