9532fe3b40 x86: link: Correct a failure in DRAM init
With the change to set up pinctrl after relocation, link fails to boot. Add
a special case in the link code to handle this.

Fixes: d8906c1f (x86: Probe pinctrl driver in cpu_init_r())

a219639d42 dm: Rename disk uclass to ahci
This started as 'ahci' and was renamed to 'disk' during code review. But it
seems that this is too generic. Now that we have a 'blk' uclass, we can use
that as the generic piece, and revert to ahci for this.

06d336cca2 x86: Create a common header for Intel register access
There are several blocks of registers that are accessed from all over the
code on Intel CPUs. These don't currently have their own driver and it is
not clear whether having a driver makes sense.

An example is the Memory Controller Hub (MCH). We map it to a known location
on some Intel chips (mostly those without FSP - Firmware Support Package).

Add a new header file for these registers, and move MCH into it.

d02be99e67 dm: pch: Remove pch_get_version op
pch_get_version op was only used by the ich spi controller driver,
and does not really provide a good identification of pch controller
so far, since we see plenty of Intel PCH chipsets and one differs
from another a lot, which is not simply either a PCHV_7 or PCHV_9.
Now that ich spi controller driver was updated to not get such info
from pch, the pch_get_version op is useless now.
