[PATCH 4/4] spi: spi-coldfire-qspi: enable RuntimePM before registering to the core

From: Wolfram Sang
Date: Fri Oct 09 2015 - 02:56:23 EST


From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

The core may register clients attached to this master which may use
funtionality from the master. So, RuntimePM must be enabled before, otherwise
this will fail.
