target/mips: Fix address space range declaration on n32
This bug is probably lurking there for so long, I cannot even git-blame
my way to the commit first introducing it.
Anyway, because n32 is also TARGET_MIPS64, the address space range
cannot be determined by looking at TARGET_MIPS64 alone. Fix this by only
declaring 48-bit address spaces for n64, or the n32 user emulation will
happily hand out memory ranges beyond the 31-bit limit and crash.
Confirmed to make the minimal reproducing example in the linked issue
behave.
