[SRU][B/raspi2][PATCH] spi: spidev: Completely disable the spidev warning

[Juerg Haefliger]

From: Phil Elwell <phil at raspberrypi.org>

BugLink: https://bugs.launchpad.net/bugs/1997763

An alternative strategy would be to use "rpi,spidev" instead, but that
would require many Raspberry Pi Device Tree changes.
