Add support for SPD5118 (Jedec JESD300-5B.01) compliant temperature sensors. Such sensors are typically found on DDR5 memory modules. The first patch of the series adds SPD5118 devicetree bindings. The second patch adds support for SPD5118 temperature sensors. The third patch adds support for configuring PEC (Packet Error Checking). This patch depends on [1] and is untested. Note: The driver introduced with this patch series does not currently support accessing the SPD5118 EEPROM, or accessing SPD5118 compatible chips in I3C mode.
