Add a driver for the integrated memory controller (iMC) SMBus engine on Intel Skylake-X / Cascade Lake-X processors (socket LGA 2066, platform X299, PCU function 8086:2085). The engine provides two SMBus channels — one per pair of DIMM slots — over which SPD EEPROMs, DDR4 thermal sensors and third-party LED controllers are accessible. Exposing it as a pair of standard Linux I2C adapters lets existing tools (i2c-tools, lm-sensors) use it without bespoke sysfs hacks. Key design decisions: - ECAM MMIO access instead of CF8/CFC port I/O (SMM traps port writes) - Dynamic MCFG table parsing for mmcfg_base (no hardcoding) - Support for SMBus BYTE_DATA and WORD_DATA transfers - devm-managed resources with automatic cleanup - Global mutex to serialize transactions across both channels sharing the same ECAM mapping Signed-off-by: Simone Chifari <simone.chifari@gmail.com>
