Add the optional 2nd clock for BG2Q's sdhci0 and sdhci1. This would let the
clock be disabled during runtime pm, so saves power a bit.

We don't want to hardcode default groups at subsystem

The DMAengine API has a long standing race condition that is inherent to
the API itself. Calling dmaengine_terminate_all() is supposed to stop and
abort any pending or active transfers that have previously been submitted.
Unfortunately it is possible that this operation races against a currently
Implement the new device_synchronize() callback to allow proper
synchronization when stopping a channel. Since the driver already makes
sure that no new complete callbacks are scheduled after the
device_terminate_all() callback has been called, all left to do in the
device_synchronize() callback
The DMAengine API has a long standing issue that is inherent to the API
itself. For a client that calls dmaengine_terminate_all() it is not
possible to properly synchronize the completion of any currently running
complete callbacks to the current context. This means it is possible to end
up with a
Add a synchronize helper function for the virt-dma library. The function
makes sure that any scheduled descriptor complete callbacks have finished
running before the function returns.
This needs to be called by drivers using virt-dma in their
device_synchronize() callback. Depending on the driver
Use the new dmaengine_synchronize() function to make sure that all complete
callbacks have finished running before the runtime data, which is accessed
in the completed callback, is freed.
This fixes a long standing use-after-free race condition that has been
observed on some systems.
