Remove filtering on RX messages on receives for 2515 chip

@JBernouli Can you explain this PR? We'd like to know the basis for your revision.

In the can settings RXB1 and RXB0 control registers are masked with 0x60 and then setting it to 00

00 = Receives all valid messages using either Standard or Extended Identifiers that meet filter criteria;
Extended ID Filter registers, RXFnEID8:RXFnEID0, are applied to the first two bytes of data in
the messages with standard IDs

This resulted in not receiving extended ID Can messages, the change i made allowed that,
i noticed however that you do have the code already in the #DEBUG_RXANY that i didnt see before,

maybe you guys are filtering on purpose? but the filters are never set up as far as i can see.

Hello,

I appreciate what you've done, but I'm not considering merging this code right now.

Since there are still some people who need the filtering feature, what we should consider is to enable the filter settings feature rather than just removing it.
