drivers: ipmi: Support raw i2c packet in IPMB

Browse Source 
Many IPMB devices don't support smbus protocol and this driver
only supports the smbus protocol at the moment.

Added support for the i2c protocol as well. There will be a variable
"i2c-protocol" passed by the device tree or ACPI table which determines
whether the protocol is i2c or smbus.

ipmb@10 {
compatible = "ipmb-dev";
reg = <0x10>;

If xmit of data to be done using raw i2c block vs smbus
then "i2c-protocol" needs to be defined as above.
