Fix missing initial value for last_value.
For GuC capture register definition, it is required to define 64bit
register in a pair of 2 consecutive 32bit register entries, low first,
then hi. Add code to check this order.
Changes from prior revs:
v5:- Correct cross-line comment format
v4:- Fix warn on condition and remove skipping
v3:- Move break inside brace
v2:- Correct the fix tag pointed commit
Add examples in comments for warning
Add 1 missing hi condition check
