ipmi: Add Loongson-2K BMC support
This patch adds Loongson-2K BMC IPMI support.
According to the existing design, we use software simulation to
implement the KCS interface registers: Stauts/Command/Data_Out/Data_In.
Also since both host side and BMC side read and write kcs status, fifo flag
is used to ensure data consistency.
The single KCS message block is as follows:
+-------------------------------------------------------------------------+
|FIFO flags| KCS register data | CMD data | KCS version | WR REQ | WR ACK |
+-------------------------------------------------------------------------+
