intel_idle: Introduce a helper for checking PC6

Introduce the skx_is_pc6_disabled() for checking if PC6 is disabled and
switch the following functions to use it:

 - skx_idle_state_table_update()
 - spr_idle_state_table_update()

At the same time, clean them up improving the commentary and moving it to
the function kernel-doc.

Purely a clean up, no functional changes intended.
