servo v4 has SD card and USB 
We would like to use either one for recovery image, I am not sure if servo_sees_usbkey need to do something different in order to check SD card also.

test:
- dut-control usb_mux_sel1:dut_sees_usbkey
- ssh to dut and ls -l /dev/sd* (according to https://cs.corp.google.com/chromeos_public/src/third_party/autotest/files/server/cros/servo/servo.py?q=probe_host_usb_dev&sq=package:%5Echromeos_public$&l=554)


I see /dev/sd* when I connect the USB stick but nothing when I connect the SD card.

Then I tried:
- dut-control sd_mux_sel:dut_sees_usbkey
- from DUT ls -l /dev/sd* return nothing

2 issues:
* The name of usb_mux_sel1 probably changed, sd_mux_sel?
* On servo v4, there are 2 extra USB mux's (names?):
    Mux to select [SD card] or [USB stick]
    Mux to select [uServo] or [DUT Type-C]
  Have to modify the switch_usbkey() method in servo.py to set the correct values for these mux's.

To enable SD on host: 
dut-control sd_en:on sd_pwr_en:on sd_mux_sel:host host_sd_usb_mux_en:on host_sd_usb_mux_sel:sd

To enable SD on DUT:
dut-control sd_en:on sd_pwr_en:on sd_mux_sel:dut


I believe Kevin was working on appropriate defaults and aliases that could make it work transparently.
