    drm/xe: Normalize bo flags macros
    
    The flags stored in the BO grew over time without following
    much a naming pattern. First of all, get rid of the _BIT suffix that was
    banned from everywhere else due to the guideline in
    drivers/gpu/drm/i915/i915_reg.h that xe kind of follows:
    
            Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
    
    Here the flags aren't for a register, but it's good practice to keep it
    consistent.
    
    Second divergence on names is the use or not of "CREATE". This is
    because most of the flags are passed to xe_bo_create*() family of
    functions, changing its behavior. However, since the flags are also
    stored in the bo itself and checked elsewhere in the code, it seems
    better to just omit the CREATE part.
    
    With those 2 guidelines, all the flags are given the form
    XE_BO_FLAG_<FLAG_NAME> with the following commands:
    
            git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \
                    -e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \
                    -e 's/XE_BO_CREATE_/XE_BO_FLAG_/g'
            git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \
                    -e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64k)/XE_BO_FLAG_\1/g'
    
    And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to
    follow the coding style.
