Subject: [PATCH] drivers: net: replace UINT64_MAX with U64_MAX
U64_MAX is well defined now while the UINT64_MAX is not, so we fall
back to drivers' own definition as below:
#ifndef UINT64_MAX
#define UINT64_MAX (u64)(~((u64)0))
#endif
I believe this is in one phy driver then copied and pasted to other phy
drivers.
Replace the UINT64_MAX with U64_MAX to clean up the source code.
