The SCP needs firmware which differs between platforms and SoCs. Add a new
property "firmware-name" to allow the DT to specify the platform/board specific
path to this firmware file.
The firmware-name property is optional and the code falls back to the
old filename if the property isn't present.

The SCP needs firmware which differs between other platforms and SoCs.
Add a new property "firmware-name" to allow the DT to specify the
platform/board specific path to this firmware file.

The SCP firmware blob differs between platforms and SoCs. We add
support in the SCP driver for reading the path of firmware file from
DT in order to allow these files to live in a generic file system
(or linux-firmware).
The firmware-name property is optional and the code falls back to the
old filename if the property isn't present.
