[virtual/kernel] Add patch to bind power supply for DuoVero's HDMI

This patch binds the power supply of HDMI to the power regulator.
The Kernel's power manager no longer shuts of the screen as it
correctly detects the regulator has a consumer.
[virtual/kernel] Enable FHANDLE and CGROUP

- FHANDLE is required to spawn a serial console on systemd managed
systems
- CGROUP and related configurations are required to mount tmpfs on
boot
[virtual/kernel] Build OMAP4 DSS and HDMI support into the Kernel

The OMAP4 display subsystem (DSS) and HDMI output support should
be built into the kernel rather than as modules.

This allows DuoVero on Parlor board outputting to a display through
the HDMI port.
