MIPS/spi: New driver for SPI master controller for OCTEON SOCs.

From: David Daney <david.daney@cavium.com>

Several members of the OCTEON family have on-chips SPI master
controller hardware, so here is a driver for it.

I split the register definitions out to a separate patch so that they
live with all the other similar files for other OCTEON hardware blocks
in arch/mips/include/asm/octeon.  This does leave the question of who
should merge these.  I don't have a preference, could be Ralf's
Linux/MIPS tree or via the SPI maintainers.

Tested by driving an at25 eeprom.

  MIPS: OCTEON: Add register definitions for SPI host hardware.
  spi: Add SPI master controller for OCTEON SOCs.
