ArmPlatformPkg: Reformat VE Memory Map code

Browse Source 
This change is purely cosmetic, with no functional impact, and only
exists to isolate cosmetic changes from a functional fix.
    Some indentation is adjusted.
    Overlength lines are re-flowed.
    alignment on = is adjusted as some lines exceeded 80 columns.
    if statement converted to conditional assignment.
    Redundant re-calculation of CacheAttributes removed.
