Patches DSSP and FHPP as Constants instead of External Objects (which is not found in any other table).
Sets DSSP to One and FHPP to Zero by default.
Tested only on Arch Linux with GRUB.
Requires sudo, iasl, cpio, sed, tee, tr and bc.
If you know what DSSP and FHPP actually stands for (e.g. which SATA features it controls) - please let me know, because i decided to enable it (by setting it to One) while looking at other SSDT1 tables with DSSP and FHPP variables on github.
