MBA fixes - AMD

[babumoger]

Couple of fixes.

1. MBA feature was broken for AMD
2. Changed printing messages from SOCKET to Core Complex for AMD

Description

The MBA feature was not working when trying to set the MBA limits on AMD. ....

pqos -I OS -e mba:1=0xf

NOTE: Mixed use of MSR and kernel interfaces to manage CAT or CMT & MBM may lead to unexpected behavior. ERROR: Expected MBA controller but not requested! SOCKET 0 MBA COS1 - FAILED! Allocation configuration error!

The code was using the hard coded value to detect the feature. Changed it to use the vendor specific mba_max values while detecting the feature.

Also fixed printing  messages on AMD.
Before the change.
SOCKET 0 MBA COS1 => 256% requested, 256% applied
SOCKET 1 MBA COS1 => 256% requested, 256% applied
SOCKET 2 MBA COS1 => 256% requested, 256% applied
SOCKET 3 MBA COS1 => 256% requested, 256% applied

After the change.

Core Complex 1 MBA COS1 => 256 requested, 256 applied
