bl30: AO PIC claim and complete consistency for rtos_sdk [1/2]

PD#SWPL-94767

Problem:
For old N205 AOCPU, whose interrupt control unit is PIC,
need to ensure consistency of the interrupt claim and
complete times, which might cause abnormal interrupt
status.

Solution:
Delete C complete function. Since it will complete in
the assembly instructions, it is redundant.
Delete restriction of complete in clearpending to ensure
one claim and one complete, even if the result of claim
is 0.

Verify:
Local test pass.
