Subject: [PATCH v2] bus: mhi: core: Fix reading wake_capable channel configuration

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.
