x86: SGI UV: Map MMIO-High memory range
UV depends on the MMRHI space being identity mapped. The patch:
x86: Make 64-bit efi_ioremap use ioremap on MMIO regions
changed this to make efi regions at a different address using
ioremap. Add the identity mapping to uv_system_init.
( Note this code was previously present but was deleted when BIOS
added the ranges to the EFI map - previous efi code identify
mapped the ranges. )
