[yocto] [meta-raspberrypi][PATCH 1/5] pitft: Add support for pitft35r

[Khem Raj]

From: Rob Woolley <rob.woolley at windriver.com>

The support for the PiTFT 3.5 inch resistive touchscreen is optional.
It may be enabled by adding the following line in local.conf:

MACHINE_FEATURES += "pitft pitft35r"
