soc/skylake/cpu: Fix Intel SpeedStep enable/disable
In an attempt at consolidation, commit 0a203d1 [1] introduced
an additional read/write of the MISC_ENABLE msr, as well a bug
which nullified the setting of Intel SpeedStep by inserting said
read/write calls in between another set of read/write calls to the
same msr. Fix by reverting to previous (simpler) implementation.
[1] soc/intel/skylake: Use CPU common library code
https://review.coreboot.org/19566
Test: boot Linux on Librem13v2, read MISC_ENABLE msr and verify
SpeedStep bit correctly set based on devicetree setting.
