When using a 36 bit dtb file, the driver complains "resource busy".

Investigating the source of the message leads one to the
gianfar_ptp_probe function.

Since the type of the device resource requested in this function
is IORESOURCE_MEM, it should use "iomem_resource" instead of
"ioports_resource".
