Subject: [PATCH v3 03/14] RISC-V: Improve SBI PMU extension related definitions

This patch fixes/improve few minor things in SBI PMU extension
definition.

1. Align all the firmware event names.
2. Add macros for bit positions in cache event ID & ops.

The changes were small enough to combine them together instead
of creating 1 liner patches.
