Simplify the handling of "power sequences". At the moment, this is rather
complicated:
The hal layer calls HalPwrSeqCmdParsing. This function takes a pointer to
a power sequence. The sequences themselves are defined as global variables
in a separate file. There's an alias for each sequence, the callers of
HalPwrSeqCmdParsing use these aliases instead of the sequences themselves.
There's no point in passing the sequences around. We can move the
sequences into the same file as the HalPwrSeqCmdParsing function where
they are used. Callers of HalPwrSeqCmdParsing can refer to a sequence by
using a numeric define rather than a pointer to the sequence.
