PCI: Always set prefetchable base/limit upper32 registers
Prior to 1f82de10 we always initialized the upper 32bits of the
prefetchable memory window, regardless of the address range used.
Now we only touch it for a >32bit address, which means the upper32
registers remain whatever the BIOS initialized them too.
It's valid for the BIOS to set the upper32 base/limit to
0xffffffff/0x00000000, which makes us program prefetchable ranges
like 0xffffffffabc00000 - 0x00000000abc00000
Revert the chunk of 1f82de10 that made this conditional so we always
write the upper32 registers and remove now unused pref_mem64 variable.
