[v2 0/2] SBI PMU improvements

[Atish Patra]

Here are two small patches for SBI PMU.

The 1st patch adds SBI PMU snapshot definitions and some boilerplate code while
the 2nd patches fixes an issue with discontigious counters.

Changes from v1->v2:
1. Removed additional check for counter1.
2. Return error in counter start/stop functions if snapshot flag is set.
