add BOARD_EC_CR50_COMM_SUPPORT to board properties
This CL add a board property indicating EC-CR50 communication
support. The target boards are Volteer,Dedede,Puff, and Zork.
It shall be detected if the H1 strap configuration value is
either 0x0E or 0xE0.
BUG=b:146567516, chromium:1027660
BRANCH=cr50
TEST=Flashed AP firmware through CCD on Grunt, Octopus, Scarlet
and Atlas.
This is the captured console log:
--- UART initialized after reboot ---
...
strap pin readings: a1:2 a9:2 a6:0 a12:0
[0.005886 Valid strap: 0xa properties: 0x41]
> brdprop
properties = 0x1141
> brdprop
properties = 0x201141
> pinmux

Flashed AP firmware on a reworked board with 1M ohm on DIOA1 and
5k ohm on DIOA9.
