drm/i915: Hoover the IPS enable/disable calls into the pre/post update hooks

Browse Source 
No reason the caller of the IPS pre/post update hooks should
be responsible for the actual IPS enab/disable. Just pull those
calls into the pre/post update hooks themselves. And while
at it let's adjust the function naming a bit to have a consistent
namespace.
