[PATCH v5 2/8] firmware: meson: sm: Thermal calibration read via secure monitor

[Ronald Claveau via B4 Relay]

From: Ronald Claveau <linux-kernel-dev at aliel.fr>

Add SM_THERMAL_CALIB_READ to the secure monitor command enum and
introduce meson_sm_get_thermal_calib() to allow drivers to retrieve
thermal sensor calibration data through the firmware interface.
