servo: Deprecate the driver of rec_mode which sends EC host command
This driver also made us hard to repurpose the rec_mode for bring-up.
Found out this rec_mode driver in arm_ec_common.xml should be
deprecated. We no longer calls this driver to trigger recovery mode.
Instead, we call another abstraction power_state:rec.
I searched through the power_state drivers, the ones access the
rec_mode control doesn't use this arm_ec way (they access the native
servo pin). So it is safe to remove the arm_ec driver.

TEST=Started servod on several ARM boards without error.
