drivers/ipmi/ocp: Add function to support OCP specific ipmi command

Add driver for OCP specific ipmi commands. With this driver, OCP
specific ipmi command can be used after implementing functions here.

TEST=Build with CB:42242 on Delta Lake, select Kconfig option:
IPMI_OCP and add device in devicetree to open this function.

Use ipmi-util in OpenBMC to dump raw data and check if this
function work.
