can: mcp25xxfd: optionally enable SPI crc commands for reads

Allow the (optional) use of SPI CRC read commands that can get enabled
via a module parameter.

In the future it may become necessary to enable this for register reads
(or at least some specific register reads) as there is a HW file that
may result in glitches on the spi bus.

Possible variants here are:
* just retry the read
* do not use some fifos (7, 15, 23, 31) at all
* test for bit flips of specific bits and retest CRC.
