greybus: arche-platform: Rename assert_wakedetect=>arche_platform_wd_irq_en

Now, since AP module does not send any signal to SVC, so it
automatically restricts the wake/detect gpio to input.
So rename assert_wakedetect() fn to arche_platform_wd_irq_en(),
as per implementation.

Testing Done: Tested on EVT1.5 platform.
