firmware: arm_scpi: add support for 64-bit sensor values
SCPI specification version 1.1 extended the sensor from 32-bit to 64-bit values in order to accommodate new sensor class with 64-bit requirements Since the SCPI driver sets the higher 32-bit for older protocol version to zeros, there's no need to explicitly check the SCPI protocol version and the backward compatibility is maintainted.
