ngd_slim: Decouple clock pause from power down/up
NGD slimbus driver itself can never send out clock pause sequence
for slimbus protocol on the HW lines since it can only be sent by
a manager device (which is controlled by ADSP when NGD driver is
instantiated from apps side).
Previously, clock pause of slimbus framework was coupled with power
down/up. That is not correct, since manager device may or may not
decide to send clock-pause on the HW lines. (e.g. if apps is inactive,
but some client on ADSP is active, clock-pause sequence won't be sent
over the bus.
Decouple power-on/off from clock pause to avoid giving incorrect
impression to clients on apps side about clock-pause state. Mark
clock-pause as unsupported by setting wakup function pointer to NULL
instead since this controller on apps cannot send it on HW lines.
