To correctly handle small (less than TARGET_PAGE_SIZE) MPU regions, we must correctly handle the case where the address being looked up hits in an MPU region that is not small but the address is in the same page as a small region. For instance if MPU region 1 covers an entire page from 0x2000 to 0x2400 and MPU region 2 is small and covers only 0x2200 to 0x2280, then for an access to 0x2000 we must not return a result covering the full page even though we hit the page-sized region 1. Otherwise we will then cache that result in the TLB and accesses that should hit region 2 will incorrectly find the region 1 information. Check for the case where we miss an MPU region but it is still within the same page, and in that case narrow the size we will pass to tlb_set_page_with_attrs() for whatever the final outcome is of the MPU lookup.
