Ported Peter's original change 86413 to main.
board-p1852-panel.c:
Add support for primary and secondary LVDS displays, and secondary HDMI display.
board-p1852-pinmux.c:
Add configuration for HDMI and LVDS
board-p1852.c:
board-p1852.h:
Support for determining which p1852 sku is in use
hdmi.c:If no edid retrieved, but there's a hardwired mode, enable it
(used to support HDMI->LVDS output on p1852 sku 2)
devices.c:added secondary display data.
