x86/resctrl: Merge AMD/Intel parse_bw() calls
Now after arch_needs_linear has been added, the parse_bw() calls are
almost the same between AMD and Intel.
The difference is '!is_mba_sc()', which is not checked on AMD. This
will always be true on AMD CPUs as mba_sc cannot be enabled as
is_mba_linear() is false.
Removing this duplication means user-space visible behaviour and
error messages are not validated or generated in different places.
