misc: amd-sbi: Add support for SB-TSI over I3C
AMD SB-TSI temperature sensors can be accessed over both
I2C and I3C buses depending on the platform configuration.
Extend the SB-TSI driver to support both I2C and I3C bus interfaces
by selecting the appropriate transport based on the probed bus type.
The driver maintains backward compatibility with existing I2C
deployments while enabling support for systems using the I3C bus.
Register both I2C and I3C drivers using module_i3c_i2c_driver() and
update the Kconfig dependency from I2C to I3C_OR_I2C.
