sparc64: Clean up 64-bit mmap exclusion defines.
Older UltraSPARC chips had an address space hole due to the MMU only
supporting 44-bit virtual addresses.
The top end of this hole also has the same value as the current
definition of PAGE_OFFSET, so this can be confusing.
Consolidate the defines for the userspace mmap exclusion range into
page_64.h and use them in sys_sparc_64.c and hugetlbpage.c
