Juergen Gross c957f1f3c4 x86/hyperv: Set MTRR state when running as SEV-SNP Hyper-V guest
In order to avoid mappings using the UC- cache attribute, set the
MTRR state to use WB caching as the default.

This is needed in order to cope with the fact that PAT is enabled,
while MTRRs are not supported by the hypervisor.
