ARM: 7515/1: integrator: check PL010 base address from resource
In the PL010 UART callback a comparison against the location of the statically allocated PL010 device is done to figure out which UART is doing the callback. This does not play well with dynamic devices such as in device tree, so let's check the base address of the memory resource inside the amba_device instead.
