greybus: es2: use a single bulk ep pair for all greybus data

Browse Source 
This matches a corresponding firmware change to declare a single
BULK EP pair for all greybus traffic and 1 BULK IN ep for ARPC.

Thus, avoiding URB submittions for all the other unused BULK IN
endpoints on the HOST side that took considerable amount
of bus time.

Testing Done:
Tested with modified AP<->APB1 loopback test and also with GPBridge
modules to ensure there are no regressions
