tools/intel_display_poller: Add a new tool that will poll various display registers

Browse Source 
intel_poller can be used to poll various display registers
(IIR,scanline/pixel/flip/frame counter, live address, etc.).

It can be used to determine eg. at which scanline or pixel count certain
events occur.
