baseboard/ite_evb: create ite_evb baseboard

The development board of it83xx and it8xxx2 have common code
and config options which are moved to baseboard ite_evb.

And we create another board for PD EVB based on baseboard ite_evb.

BUG=none
BRANCH=none
TEST=on baseboard ite_evb:
1.test board it83xx_evb and it8xxx2_evb:
successfully Flash EC image and boot on chip it8320 and
it83202.

2.flashrom by ite_spi test:
