drivers/ipmi: Add chip ops
* Add chips ops for IPMI KCS.
* Get IPMI version over KCS.
* Generates ACPI SPMI table for IPMI KCS.
* Generates SMBIOS type 38 for IPMI KCS.
* Generates ACPI SPMI device for IPMI KCS on LPC device.
* Add documentation
To use this driver on BMC that support KCS on I/O:
1. Add an entry to the devicetree.cb:
chip drivers/ipmi
device pnp ca2.0 on end # IPMI KCS
end
2. Select IPMI_KCS in Kconfig.
3. (Optional) enable LPC I/O decode for the given address.
Tested on Wedge100s.
