Nishanth Menon efe4e06de3 PM / AVS: SmartReflex: disable errgen before vpbound disable 
vpboundsintr_en is available inside the IP block as an re-sycned
version and one which is not. Due to this, there is an 1 sysclk
cycle window where the SR_SInterruptz signal could be asserted low.
IF, intr_en is cleared on the exact same cycle as the irqclr, an
additional pulse is generated which indicates for VP that
an additional adjustment of voltage is required.

This results in VP doing two voltage adjustments for the SRERR
(based on configuration, upto 4 steps), instead of the needed
1 step.
Due to the unexpected pulse from AVS which breaks the AVS-VP
communication protocol, VP also ends up in a stuck condition by
entering a state where VP module remains non-responsive
to any futher AVS adjustment events. This creates the symptom
called "TRANXDONE Timeout" scenario.

By disabling errgen prior to disable of intr_en, this situation
can be avoided.
