Message:

1. Rewrite and clean fat_get_cluster_fat12
2. Support MIPS and other arch with only alligned memory access.
3. Fix incompatibilities with BigEndian.
4. Tested on IA32 and on MIPS32 EndianBig (GXEmul):

FAT12,16 reading and writing. FAT32 only reading. FAT32 writing - not tested!

5. Some fixes for FAT32: reading hi and lo part of node cluster number from fat_dentry_t,

but its need more fixes to change size of cluster number from uint16_t to uint32_t etc.
