I have considered to put this in driver, however, different Atmel SoC
have different attributes for each endpoint and different number of
endpoint.
for example;
at91sam9x5: EP("ep1", 1, 1024, 2, 1, 1)
sama5d3x: EP("ep1", 1, 1024, 3, 1, 0)
So, if I put this in driver, there will be many #ifdef. If newly SoC
added, maybe we will need to add #ifdef again. So, I put it here.
