This patch set adds Xilinx AXI Multirate MAC(MRMAC) driver support.

This MRMAC is a high performance, low latency, adaptable Ethernet integrated
hard IP. This can be configured up to four ports with MAC rates from 10GE to
100GE.

Supported Configuration Combinations:
1 × 100GE
2 × 50GE
1 × 40GE
4 × 25GE
4 × 10GE

Currently added support and tested below configurations in the driver:
4 × 25GE
4 × 10GE

Changes in v3:
 - In V2 by mistake changed return type of isrxready() of xilinx_axi_emac
   driver instead of xilinx_axi_mrmac driver. Fixed it in V3.

Changes in v2:
 - Changed all static allocations to dynamic and freed them.
 - Used setbits_le32 and clrbits_le32 wherever applicable
 - All return's are changed to proper error codes instead of 1 or -1
 - Changed return type of isrxready() from int to bool
 - Changed all printf's to log_warning, and debug to log_debug
 - Added function headers with desciption
 - Changed all capital hex numbers to small hex numbers
