Add NTB_HWERR_BAR_ALIGN hw errata flag to work around issue where the
aligment for the XLAT base must be BAR size aligned rather than 4k page
aligned. On ICX platform, the XLAT base can be 4k page size aligned
rather than BAR size aligned unlike the previous gen Intel NTB. However,
a silicon errata prevented this from working as expected and a workaround
is introduced to resolve the issue.

Adding 4th generation Intel NTB support bits. There are a lot of common
parts that the gen4 NTB has with gen3 NTB on Skylake. The commonalities are
reused in gen4 Icelake NTB.
