sparc64: Define VA hole at run time, rather than at compile time.

[ Upstream commit 4397bed080598001e88f612deb8b080bb1cc2322 ]

Now that we use 4-level page tables, we can provide up to 53-bits of
virtual address space to the user.

Adjust the VA hole based upon the capabilities of the cpu type probed.
