tools/power turbostat: fix Skylake Xeon package C-state display
Turbostat neglects to display all package C-states for some Skylake Xeon BIOS configurations.
This is due to a typo in the table decoding MSR_PKG_CST_CONFIG_CONTROL (0x000000e2)
Here we fix that typo, according to Intel SDM, vol 4, Table 2-41 -
"MSRs Supported by Intel® Xeon® Processor Scalable Family with DisplayFamily_DisplayModel 06_55H".
