powercap/drivers/dtpm: Convert the init table section to a simple array
The init table section is freed after the system booted. However the
next changes will make per module the DTPM description, so the table
won't be accessible when the module is loaded.
In order to fix that, we should move the table to the data section
where there are very few entries and that makes strange to add it
there.
The main goal of the table was to keep self-encapsulated code and we
can keep it almost as it by using an array instead.
