misc: amd-sbi: Clarify that this is a BMC driver

2025-10-22T06:02:57Z

Add a sentence to the driver description to clarify that the sbrmi-i2c driver is intended to run on the BMC and not on the managed node. Add platform dependencies accordingly.

misc: amd-sbi: Add support for SB-RMI over I3C

2025-10-22T05:59:57Z

AMD EPYC platforms with zen5 and later support APML(SB-RMI) connection to the BMC over I3C bus for faster data transfer up to 12.5 Mhz. I2C and I3C is supported in same file using module_i3c_i2c_driver() with probe based on dts entry. AMD APML I3C devices support static address for backward compatibility to I2C. I3C static address can be used to assign I3C device dynamic address.
