[PATCH RFC 3/6] ARM: qcom_defconfig: add display-related options

[Brian Masney <masneyb@onstation.org>]

Add the CMA (Contiguous Memory Allocator) for the MSM DRM driver, the
simple panel, and the TI LM3630A driver in order to support the display
on the LG Nexus 5 (hammerhead) phone.

Signed-off-by: Brian Masney <masneyb@onstation.org>
---
The panel and backlight are currently compiled into the kernel, but will
be moved to be modules once the display is fully working in a later
verison of this patch series.
