2d84b46e96 Ensure PMF service timestamps are properly aligned on a cache line boundary
When using more than a single service in PMF, it is necessary that the
per-service timestamps begin on a cache line boundary.  Previously it
was possible that two services shared a cache line for their
timestamps.  This made it difficult to reason about cache maintenance
operations within a single service and required a global understanding
of how all services operate.

d2e201b429 Rename pmf_calc_timestamp_offset to pmf_calc_timestamp_addr
The macro calculates an absolute address rather than an offset so
rename it to avoid confusion.

5695cfe77f Add assembler helper to calculate PMF timestamp offset
Given the service name and timestamp id, this assembler macro
calculates the offset into a memory region where the per-cpu timestamp
value is located.

afdda571f1 Move pmf headers to include/lib/pmf
More headers will be needed soon so better to move these to their own
directory to avoid cluttering include/lib.
