[U-Boot] [PATCH V3 27/31] net: fec: fix build warnings for 64bits support

From: Ye Li <ye.li at nxp.com>
When building for 64bits system, we get some warnings about type
cast between pointer and integer. This patch eliminates the warnings
by using ulong/long type which is 32bits on 32bits system or 64bits on
64bits system.
