zephyr: shim: handle sidesel in the shim file
This adds handling for the sidesel channel from the shim driver, if the
sidesel node is specified.
With this, all the pwm-led combinations should be manageable from the
shim driver, so this also removes the conditionals from volteer driver
and drops it from the Zephyr build entirely.
BRANCH=none
BUG=b:177452529
TEST=build and run on volteer
TEST=checked the binary output if node not defined
