spi: spidev: Use 'new_id' sysfs file for enabling spidev
Use sysfs new_id file to enable spidev at runtime. new_id file accepts
bus number and chip select in 'B.C' format.
With reference to the last ML discussion here[1] regarding the solution
for spidev with device trees. This patch adds support to load spidevB.C
via sysfs new_id file as suggested by Greg.
