Subject: [PATCH 4/7] tools/power turbostat: update HWP dump to decimal from hex

From: Len Brown <len.brown@...el.com>

Syntax only.

The HWP CAPABILTIES and REQUEST ratios are more easily
viewed in decimal -- just multiply by 100 and you get MHz...

new:
cpu0: MSR_HWP_CAPABILITIES: 0x010c1b23 (high 35 guar 27 eff 12 low 1)
cpu0: MSR_HWP_REQUEST: 0x80002301 (min 1 max 35 des 0 epp 0x80 window 0x0 pkg 0x0)

old:
cpu0: MSR_HWP_CAPABILITIES: 0x010c1b23 (high 0x23 guar 0x1b eff 0xc low 0x1)
cpu0: MSR_HWP_REQUEST: 0x80002301 (min 0x1 max 0x23 des 0x0 epp 0x80 window 0x0 pkg 0x0)
