Add OEM Command to Read Mailbox PFR Registers

This OEM command allows user to read PFR mailbox
registers by specifying register address, no of
bytes to read and register identifier
(single byte or FIFO register)
Below command supports reading of single byte and
 FIFO registers

ipmitool raw 0x3e 0x84 [Register Address] [No of Bytes to Read] [Register Identifier]
Note: Register Identifier:0 for single byte read register
      Register Identifier:1 for FIFO read register

Tested:
1.Single Byte Register Testing:
  a.ipmitool raw 0x3e 0x84 0x08 13 0:
    Successfully returned 13 bytes starting from the single byte read register address 0x08.
2.FIFO Read Register Testing:
  a.ipmitool raw 0x3e 0x84 0x08 13 1:
    Successfully returned 13 bytes from the FIFO address 0x08.
3.When Register Identifier is not 0 or 1 command will fail.
4.When either of register address or no of bytes is zero the command will fail.
