The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Use devm_ioremap_resource instead of devm_request_and_ioremap.
This was done using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci
and various manual modifications to move associated calls to
platform_get_resource closer to the resulting call to devm_ioremap_resource
and to remove the associated error handling code.
The initialization of port->mapbase is also moved lower, to take advantage
of the NULL test on res performed by devm_ioremap_resource.

This patch adds support to ASC (asynchronous serial controller)
driver, which is basically a standard serial driver. This IP is common
across all the ST parts for settop box platforms.
ASC is embedded in ST COMMS IP block. It supports Rx & Tx functionality.
It support all industry standard baud rates.
