Trailing newlines before closing the function are best forgotten, or
else checkpatch moans.

drm/i915/gt: Consolidate the CS timestamp clocks
Pull the GT clock information [used to derive CS timestamps and PM
interval] under the GT so that is it local to the users. In doing so, we
consolidate the two references for the same information, of which the
runtime-info took note of a potential clock source override and scaling
factors.

drm/i915/gt: Fix up clock frequency
The bspec lists both the clock frequency and the effective interval. The
interval corresponds to observed behaviour, so adjust the frequency to
match.
v2: Mika rightfully asked if we could measure the clock frequency from a
selftest.

drm/i915/gt: Use the RPM config register to determine clk frequencies
For many configuration details within RC6 and RPS we are programming
intervals for the internal clocks. From gen11, these clocks are
configuration via the RPM_CONFIG and so for convenience, we would like
to convert to/from more natural units (ns).
