Subject: [PATCH 06/10] bus: mhi: core: Fix reading wake_capable channel configuration

From: Bhaumik Bhatt <quic_bbhatt@...cinc.com>

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.

Fixes: 0cbf260820fa ("bus: mhi: core: Add support for registering MHI controllers")
