Randall Spangler 00ea73ab16 usb_i2c: Fail if board I2C bridge is disabled ...

Add usb_i2c_board_is_enabled().

On Cr50, this is now also connected to the I2C CCD capability.  The
USB-I2C bridge can only be used when the capability is available.

On other platforms (Servo V4, etc.) where usb_i2c_board_enable() is
a no-op, add a dummy implementation which always returns true.

See go/cr50-ccd-wp for more information.

BUG=b:62537474
BRANCH=cr50
TEST=manual with CR50_DEV=1
	Connect host PC to dev board USB port
	On host PC:
		sudo servod -c ccd_cr50.xml -c reef_r1_inas.xml
		dut-control pp3300_ec_shv_reg --> fail, error 0x8001

	ccdoops --> reset I2C config
	ccd i2c disable --> I2C disabled

	On host PC:
		sudo servod -c ccd_cr50.xml -c reef_r1_inas.xml
		dut-control pp3300_ec_shv_reg --> fail, error 0x0006

	ccd i2c enable --> I2C enabled
	ccdunlock --> I2C disabled
	ccdoops --> I2C enabled
	ccdset i2c unlesslocked
	ccdlock --> I2C disabled
	ccdunlock --> I2C enabled
