meta-bletchley: motor-ctrl:check ac status before on/off and refine dfu cmd

a)
Block power on/off cmd if ac-relay is off.

b)
From official User Guide, to enter DFU mode must disconnect
the Host from power for at least 10 seconds, but power from
ac relay board maybe not be disappear immediately while pull
ac-relay control gpio to low.

Base on experiment result, expand wait time to 25 sec for
workaround.

Example:
a) When sled2 is ac-off
root@bletchley:/# power-ctrl sled2 on
sled2 is ac-off, please turn on ac before power on
root@bletchley:/# power-ctrl sled2 off
sled2 is already ac-off

b)
Tested 10 times into dfu mode successfully
root@bletchley:/# power-ctrl sled2 dfu
Set host2 DFU mode
SLED2: turn ac-off
set_gpio: set power-host2 = 0 success
SLED2: pressing power button
Motor go forward to press Power button
Power button switch triggered
SLED2: turn ac-on
set_gpio: set power-host2 = 1 success
SLED2: releasing host power button
Motor reverse to initial position successful
