CHROMIUM: spring: dts: Instantiate s5m8767 PMIC.

Note, this will enumerate multiple PMICs for the same design as the
max77686 PMIC is also enumerated via cros5250-common.dtsi.  This is
remedied by the firmware (u-boot) at boot time by pruning the
non-existent PMIC.

  See: https://gerrit.chromium.org/gerrit/#/c/41993/ for details.

CL also disables ADC node for Spring which is unused.

BUG=chrome-os-partner:16430
TEST=kernel compiles for BOARD=daisy_spring
