cpu/intel/common: improve debug output
currently, if the IA32_FEATURE_CONTROL lock bit is already
set, VMX status isn't reported. Adjust debug output to
provide more useful infomation on both VMX and lock bit statuses.
Test: build/boot google/chell, observe useful output in cbmem log
regardless of lock bit status.
