The 'wake-capable' entry in channel configuration is not set when
parsing the configuration specified by the controller driver. Add
the missing entry to ensure channel is correctly specified as a
'wake-capable' channel.

Looks like this one is qualified as a bug fix. Please add the fixes tag and Cc
stable.

And the subject could be,
"bus: mhi: core: Fix reading wake_capable configuration"

Thanks,
Mani
