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
