usb: gadget: pxa27x_udc: Replace in_interrupt() usage in comments

The usage of in_interrupt() in drivers is phased out for various reasons.

Documenting calling contexts of functions with 'in_interrupt()' or
'!in_interrupt()' is imprecise: For a function which might sleep the
condition is preemptible task context, which is not what '!in_interrupt()'
describes.

Replace the context docummentation with plain text and make them match
reality.
