dev, kernel: AHCI, HeFS filesystem, SysChk, and BootSATA improvements.

what?
 - AHCI now writes to disk, forgot to do it.
 - Codebase's architecutre has been used to reuse the Generic+AHCI driver in SysChk for AHCI. (tradeoff is 256K in size instead of 36K)
 - DriveMgr now detects EPM.
 - And HeFS is still being worked on.
