i2c: amd-asf: Add i2c_algorithm operations to support AMD ASF with SMBus

Implement the i2c_algorithm operations to enable support for AMD ASF
(Alert Standard Format) with SMBus. This enhancement includes:

- Adding functionality to identify and select the supported ASF functions.
- Implementing mechanisms for registering and deregistering I2C slave
  devices.
- Providing support for data transfer operations over ASF.

Additionally, include a 'select' Kconfig entry as the current patch
utilizes .reg_slave() and .unreg_slave() callbacks, which are controlled
by CONFIG_I2C_SLAVE.
