powercap: intel_rapl: Change primitive order
The same set of operations are shared by different Powert Limits,
including Power Limit get/set, Power Limit enable/disable, clamping
enable/disable, time window get/set, and max power get/set, etc.
But the same operation for different Power Limit has different
primitives because they use different registers/register bits.
A lot of dirty/duplicate code was introduced to handle this difference.
Instead of using hardcoded primitive name directly, using Power Limit id
+ operation type is much cleaner.
For this sense, move POWER_LIMIT1/POWER_LIMIT2/POWER_LIMIT4 to the
beginning of enum rapl_primitives so that they can be reused as
Power Limit ids.
No functional change.
