ARC: [tlb-miss] Extraneous PTE bit testing/setting
* No need to check for READ access in I-TLB Miss handler
* Redundant PAGE_PRESENT update in PTE
Post TLB entry installation, in updating PTE for software accessed/dity
bits, no need to update PAGE_PRESENT since it will already be set.
Infact the entry won't have installed if !PAGE_PRESENT.
