tools/power turbostat: version 2026.02.14

Since release 2025.12.02:

Add L2 statistics columns for recent Intel processors:
	L2MRPS = L2 Cache M-References Per Second
	L2%hit = L2 Cache Hit %

Sort work and output by cpu# rather than core#

This commit:
	Version number and white space (indent -l160)
	No functional change.
