Restore SeaBIOS 9029a010 update, but with AHCI fix
I fixed the AHCI bug, with a patch that I wrote. It works by
restoring the old SeaBIOS AHCI initialisation behaviour, whereby
the AHCI controller is enabled from its current state; the patch
that broke AHCI in coreboot (tested on ThinkPad T420), changed
AHCI initialisation behaviour so that the controller's state is
first reset, prior to enablement.
However, my patch also retains the new AHCI initialisation
behaviour, when a CSM is in use. The AHCI reset patch was done,
by the author, specifically for SeaBIOS in CSM mode, so it makes
sense to only change the behaviour conditionally according to that.
This reverts commit 8245f0b3211812ac818adadd6526b0b39c63f3f0.
