test: driver for generic memory mapped system timer
This patch introduces the framework for implementing a driver
for a generic memory mapped system timer periperal.
It will be used to implement the driver for AP REFCLK Generic timer
which will serve as a second source of secure interrupt.
Most of the code has been adopted from tf-a-tests, a sister project
in trustedfirmware.org
