x86/generic: use HIGHMEM64G instead of HIGHMEM4G to fix PAE and Xen

Browse Source 
This is a backport of 641a65fd06 in master.

This change re-enables PAE for the 32-bit x86 subtarget, which is
interesting in its own right but also necessary for Xen support.

Commit af1d1ebd ("x86: enable 4G high memory support for generic (32bit)
subtarget") inadvertently disabled both PAE and Xen support.

Fixes: FS#908
