[meta-freescale] [fsl-community-bsp-platform][PATCH] setup-environment: add options for the script

[Mahesh Mahadevan]

Add options to the script machine, below are the options added:

. ./setup-environment --help

Usage: source setup-environment build-dir

If build-dir is not specified the current directory is used.

By default the script will setup MACHINE to be imx6qsabresd.

Supported machines: imx23evk imx28evk imx31pdk imx35pdk imx51evk imx53ard imx53qsb imx6dlsabresd imx6qsabreauto imx6qsabresd imx6slevk cgtqmx6 imx233-olinuxino-maxi imx233-olinuxino-micro imx233-olinuxino-mini imx6qsabrelite nitrogen6x wandboard-dual wandboard-solo

To build for a machine listed above, run this script as:
MACHINE=<machine> source setup-environment build-dir

The script sets PARALLEL_MAKE & BB_NUMBER_THREADS to 4
