Marcin Wojtas 472d4784a8 Add WC support for arm64 in the ENA driver 
As the pmamp_change_attr() is public on arm64 since r351131, it can be
used on the arm64 to map memory range as with the write combined
attribute.

It requires the driver to use generic VM_MEMATTR_WRITE_COMBINING flag
instead of the x86 specific PAT_WRITE_COMBINING.
