topology: replace custom attribute macros with standard DEVICE_ATTR*
Currently couple of custom macros are defined to declare the device attributes. However there are already standard macros defined in device.h that suffice the need and these custom macros can be removed. This patch replaces custom attribute macros with standard DEVICE_ATTR_RO attribute Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
