Subject: [PATCH] gianfar_ptp: use iomem, not ioports resource tree in probe

From: Wei Yang <Wei.Yang@...driver.com>

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".
