Adds cxgbe poll mode driver for DPDK under drivers/net/cxgbe directory. This
patch:
1. Adds the Makefile to compile cxgbe pmd.
2. Registers and initializes the cxgbe pmd driver.
Enable cxgbe PMD for compilation and linking with changes to:
1. config/common_linuxapp to add macros for cxgbe pmd.
2. drivers/net/Makefile to add cxgbe pmd to the compile list.
3. mk/rte.app.mk to add cxgbe pmd to link.
Update MAINTAINERS file to claim responsibility for the cxgbe PMD.

Makefile.
- Use RTE_DIM macro for calculating ARRAY_SIZE.
v2:
- Move files to new directory under drivers/net/cxgbe and update commit log.
- Move eth_dev_ops to separate patches.
- Update cxgbe Makefile to use relative rather than absolute path of pmd.
- Replace bitwise operations in fls() with gcc's __builtin_clz().
- Fix an issue in adap_init0_tweaks() related to rx_dma_offset.
