Message:

usbhost bus: refactor the bus ops

This way, method names better represent the entity it is working with.
Their semantics was shifted a bit.

Regarding the tree of structures:

bus ← device ← endpoint ← batch

Previously, devices were kept in DDF function nodes, and endpoints had
pointer to the bus and device. Now, devices have pointer to bus,
endpoints don't.

Pointer to hcd_t in bus is WIP, and will be removed.
