target/arm: Restrict the values of DCZID.BS under TCG
We can simplify our DC_ZVA if we recognize that the largest BS
that we actually use in system mode is 64. Let us just assert
that it fits within TARGET_PAGE_SIZE.
For DC_GVA and STZGM, we want to be able to write whole bytes
of tag memory, so assert that BS is >= 2 * TAG_GRANULE, or 32.
