spi: spidev: Add spidev patch to silence warning about spidev listing in DT
spidev is the userspace interface to the SPI subsystem.
many other platforms, use a compatible string of "spidev"
to cause the spidev module to be loaded. A new commit in
the upstream 4.1 branch (956b200) demonstrates the author's
objection to this practice by causing the module to WARN
when it detects that usage. Add the "spidev" string to compatible
to silence this warning.
