ec/google/chromeec: Update ec_commands.h

Copy ec_commands.h directly from ChromiumOS EC repository (CL:1520574).

Since ec_commands.h already defines usb_charge_mode and only
USB_CHARGE_MODE_DISABLED is used in coreboot, enum usb_charge_mode is
removed from ec.h.

To avoid redefinition of the BIT macro, #ifndef check is added to
include/types.h.
