[PATCHv5 2/8] TEMP: ARM: OMAP4: hwmod_data: Do not get DSP out of reset at boot time

From: Rajendra Nayak <rnayak at ti.com>

With no driver handling DSP, if brought out of reset, it stays
active and does not assert standby. This leads to IVAHD powerdomain not
transitioning and hence preventing chip retention.

This patch is no longer needed once Paul's powerdomain fixes are merged:
