efi/uga: Use 64 bit for fb_base
...
We get 64 bit from PCI BAR but then truncate by assigning to 32 bit.
Make sure to check that pointer does not overflow on 32 bit platform.

efi/uga: Fix PCIe LER when GRUB2 accesses non-enabled MMIO data from VGA
...
A GPU inserted into a PCIe I/O slot disappears during system startup.
The problem centers around GRUB and a specific VGA init function in
efi_uga.c. This causes an LER (Link Error Recorvery) because the MMIO
memory has not been enabled before attempting access.
The fix is to add the same coding used in other VGA drivers, specifically
to add a check to insure that it is indeed a VGA controller. And then
enable the MMIO address space with the specific bits.
