p9_mss_setup_bars -- customize interleave granularity
create new attribute to encapsulate system-wide interleave
granularity, ship default should be 128B (so that the stride
between channels in a group is a single cacheline)
other enums are supported for logic and performance verification
update p9_mss_setup_bars HWP to apply granularity customization
only for supported group sizes of 2, 4, and 8
