Currently, the GRUB payload for coreboot does not detect the Western
Digital hard disk WDC WD20EARS-60M AB51 connected to the ASRock E350M1,
as that takes over ten seconds to spin up.

disk/ahci.c:621: cleaning up failed devs
```
GRUB detects the drive, when either unloading the module *ahci*, and
then loading it again, or when doing a warm reset.
As the ten second time-out is too short, increase it to 32 seconds,
used by SeaBIOS. which detects the drive successfully.
The AHCI driver in libpayload uses 30 seconds, and that time-out was
added in commit 354066e1 (libpayload: ahci: Increase timeout for
signature reading) with the description below.
> We can't read the drives signature before it's ready, i.e. spun up.
> So set the timeout to the standard 30s. Also put a notice on the
> console, so the user knows why the signature reading failed.
