[PATCH v2 10/10] MIPS: generic: Add optional support for Android kernel

[Aleksandar Markovic <aleksandar.markovic@rt-rk.com>]

From: Miodrag Dinic <miodrag.dinic@imgtec.com>

This commit adds new android.config configuration file including
the most common prerequisites for running Android operating system.

The selected set of platform independent configuration parameters
have been taken from the official Android kernel repo:
https://android.googlesource.com/kernel/common/+
/android-4.4/android/configs/android-base.cfg

android.config will be merged with the selected generic kernel
configuration only if explicitly specified through environment
variable OS=android.

Example:
make ARCH=mips 64r6el_defconfig BOARDS="list of boards" OS=android

android.config file should be occasionally revisited and updated
with latest requirements from Google.
