ARM: DRA7: hwmod: Add VIP nodes

This patch adds the required hwmod entries to support the Video
Input Port (VIP) for the DRA7 family of devices.

- Added VIP1 hwmod entry in the DRA7x generic section.
- Added VIP2 hwmod entry in the DRA74x section.
- Added VIP3 hwmod entry in the DRA74x section.
- Added VIP2 hwmod entry in the DRA76x section.

DRA75x_DRA74x_ES1.1 Version T Technical Reference Manual
(Literature Number SPRUHI2T) states VIP only support NO_STANDBY,
FORCE_STANDBY, NO_IDLE, FORCE_IDLE and SMART_IDLE.
The hwmod flags were set to reflect this fact and make sure that
both are software supervised (SWSUSP).
