Update Chelsio gige net driver.

- Use extern prefix for functions required.
- Removed a lot of wrappers, including t1_read/write_reg_4.
- Removed various macros, using native kernel calls now.
- Enumerated various #defines.
- Removed a lot of shared code which is not currently used in "NIC only" mode.
- Removed dead code.

Documentation/networking/cxgb.txt:
- Updated release notes for version 2.1.1

drivers/net/chelsio/ch_ethtool.h
- removed file, no longer using ETHTOOL namespace.

drivers/net/chelsio/common.h
- moved code from osdep.h to common.h
- added comment to #endif indicating which symbol it closes.

drivers/net/chelsio/cphy.h
- removed dead code.
- added comment to #endif indicating which symbol it closes.

drivers/net/chelsio/cxgb2.c
- use DMA_{32,64}BIT_MASK in include/linux/dma-mapping.h.
- removed unused code.
- use printk message for link info resembling drivers/net/mii.c.
- no longer using the MODULE_xxx namespace.
- no longer using "pci_" namespace.
- no longer using ETHTOOL namespace.

drivers/net/chelsio/cxgb2.h
- removed file, merged into common.h

drivers/net/chelsio/elmer0.h
- removed dead code.
- added various enums.
- added comment to #endif indicating which symbol it closes.

drivers/net/chelsio/espi.c
- removed various macros, using native kernel calls now.
- removed a lot of wrappers, including t1_read/write_reg_4.

drivers/net/chelsio/espi.h
- added comment to #endif indicating which symbol it closes.

drivers/net/chelsio/gmac.h
- added comment to #endif indicating which symbol it closes.

drivers/net/chelsio/mv88x201x.c
- changes to sync with Chelsio TOT.

drivers/net/chelsio/osdep.h

  - removed various macros, using native kernel calls now.
  - removed a lot of wrappers, including t1_read/write_reg_4.
  - removed unused code.

  drivers/net/chelsio/regs.h
  - added a few register entries for future and current feature support.
  - added comment to #endif indicating which symbol it closes.

  drivers/net/chelsio/sge.c
  - rewrote large portion of scatter-gather engine to stabilize
  performance.
  - using u8/u16/u32 kernel types instead of __u8/__u16/__u32 compiler
  types.

  drivers/net/chelsio/sge.h
  - rewrote large portion of scatter-gather engine to stabilize
  performance.
  - added comment to #endif indicating which symbol it closes.

  drivers/net/chelsio/subr.c
  - merged tp.c into subr.c
  - removed various macros, using native kernel calls now.
  - removed a lot of wrappers, including t1_read/write_reg_4.
  - removed unused code.

  drivers/net/chelsio/suni1x10gexp_regs.h
