firmware: arm_scpi: improve info message for pre-1.0 firmware
On legacy pre-1.0 firmware versions so far the following message is printed which may cause some confusion: SCP Protocol 0.0 Firmware 0.0.0 version Therefore replace the message with the following if firmware doesn't provide usable version information: SCP Protocol legacy pre-1.0 firmware Tested-by: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
