arm32: dynamic user va range

core_mmu_get_user_va_range() selects user va range. No change in user TA
va address when configured with V7 MMU tables.

When configured with LPAE only use TTBR0. The top L0 table is CPU
specific with all entries common except one which is used when mapping
user TAs. User TA va range is dependent on the first unused L0 entry.
