  1. ace: mm: tlb: Ignore unmappig error in driver initalization 

    The sys_mm_drv_unmap_region_initial function is responsible for unmapping
all unused virtual memory during tlb driver initialization. Most addresses
will not have a mapped page. Ignore the error code indicating unmapped
memory that will occur when trying to unmap.

  2. ace: mm: tlb: Check tlb translation enabled before flushing cache 

    Before unmapping a memory page, the cache is flushed. If the given memory
page is not mapped, this operation ends with a cpu exception on the
ptl platform. Add check if tlb translation is active before flushing.
