driver: net: fsl-mc: Add DPAA2 commands to manage MC
Management complex Firmware, DPL and DPC are depolyed during u-boot boot sequence. Add new DPAA2 commands to manage Management Complex (MC) i.e. start mc, aiop and apply DPL from u-boot command prompt.

+DPAA2 commands to manage Management Complex (MC)
+------------------------------------------------
+DPAA2 commands has been introduced to manage Management Complex
+(MC). These commands are used to start mc, aiop and apply DPL
+from u-boot command prompt.
+
+Please note Management complex Firmware(MC), DPL and DPC are no
+more deployed during u-boot boot-sequence.
+
+Commands:
+a) fsl_mc start mc <FW_addr> <DPC_addr> - Start Management Complex
+b) fsl_mc apply DPL <DPL_addr> - Apply DPL file
+c) fsl_mc start aiop <FW_addr> - Start AIOP
+
+How to use commands :-
+1. Command sequence for u-boot ethernet:
+ a) fsl_mc start mc <FW_addr> <DPC_addr> - Start Management Complex
+ b) DPMAC net-devices are now available for use
+
+ Example-
+ Assumption: MC firmware, DPL and DPC dtb is already programmed
+ on NOR flash.
+
+ => fsl_mc start mc 580300000 580800000
+ => setenv ethact DPMAC1@xgmii
+ => ping $serverip
+
+2. Command sequence for Linux boot:
+ a) fsl_mc start mc <FW_addr> <DPC_addr> - Start Management Complex
+ b) fsl_mc apply DPL <DPL_addr> - Apply DPL file
+ c) No DPMAC net-devices are available for use in u-boot
+ d) boot Linux
+
+ Example-
+ Assumption: MC firmware, DPL and DPC dtb is already programmed
+ on NOR flash.
+
+ => fsl_mc start mc 580300000 580800000
+ => setenv ethact DPMAC1@xgmii
+ => tftp a0000000 kernel.itb
+ => fsl_mc apply dpl 580700000
+ => bootm a0000000
+
+3. Command sequence for AIOP boot:
+ a) fsl_mc start mc <FW_addr> <DPC_addr> - Start Management Complex
+ b) fsl_mc start aiop <FW_addr> - Start AIOP
+ c) fsl_mc apply DPL <DPL_addr> - Apply DPL file
+ d) No DPMAC net-devices are availabe for use in u-boot
+ Please note actual AIOP start will happen during DPL parsing of
+ Management complex
+
+ Example-
+ Assumption: MC firmware, DPL, DPC dtb and AIOP firmware is already
+ programmed on NOR flash.
+
+ => fsl_mc start mc 580300000 580800000
+ => fsl_mc start aiop 0x580900000
+ => setenv ethact DPMAC1@xgmii
+ => fsl_mc apply dpl 580700000
