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. Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Signed-off-by: David S. Miller <davem@davemloft.net>
