[PATCH v2 6/7] OMAP4: DSS: Adding a picodlp in OMAP4430 SDP board file

[Mayuresh Janorkar <mayur@ti.com>]

An on-board panel named picodlp projector is available for OMAP4430 SDP.

Entry for this panel is being added in dss_devices in the board file.
It also needs 4 GPIO pins and are defined and used in board file.
picodlp also needs an i2c client over i2c controller-2 at address 0x1b.
