On Haswell platforms, the processor and the PCH are two separate dies,
and communicate through a high-speed bus. This is DMI (Direct Media
Interface) on traditional two-package platforms, but single-package
Haswell LP variants use OPI (On-Package Interconnect) instead.
Since OPI is not routed through the mainboard, most link parameters are
static and cannot be changed. OPI self-initializes on boot, anyway.
However, DMI needs to be initialized in firmware. On Haswell, the MRC
initializes the physical DMI link, but things like topology and power
management need to be configured as well. And we don't do that properly.
We enable ASPM on the PCH side of the DMI link, but not on the SA side.
Both sides need to use the same settings, so enable DMI ASPM on the SA.
Clearing the error status bits needs to be done on all Haswell variants.
Tested on Asrock B85M Pro4, still boots.

The Kconfig lint tool checks for cases of the code using BOOL type
Kconfig options directly instead of with CONFIG() and will print out
warnings about it. It gets confused by these references in comments
and strings. To fix it so that it can find the real issues, just
update these as we would with real issues.

There's no generic way to tell whether a mainboard has an EC or not.
Making Kconfig symbols for these options seems overkill, too. So, just
put them on the devicetree. Also, drop unnecessary assignments when the
board's current value is zero, as the struct defaults to zero already.
