cpufreq: intel_pstate: Fix processing for turbo activation ratio
When the config TDP level is not nominal (level = 0), the MSR values for
reading level 1 and level 2 ratios contain power in low 14 bits and actual
ratio bits are at bits [23:16]. The current processing for level 1 and
level 2 is wrong as there is no shift done to get actual ratio.
Fixes: 6a35fc2d6c22 (cpufreq: intel_pstate: get P1 from TAR when available)
