[PATCH] fix IORESOURCE_MEM_xxx usage in dm9k driver

[zzs213 at 126.com]

From: 张忠山 <zzs213 at 126.com>

Because the const used in dm9k driver unmatch the new IORESOURCE_MEM_xxx
macro. So whenever the driver start probe, the flowwing error message
appear:

        Wrong io resource size

This patch fix this.
