[Mingkai Hu]

This patchset refactor the file spi_mpc8xxx.c to abstract some common 
code as a lib used by the SPI/eSPI controller driver, move the SPI 
controller driver code to spi_fsl_spi.c, and add the eSPI controller 
support with spi_fsl_espi.c.

v4 main change:
 - Update to the latest kernel base(Linux 2.6.36-rc7).
 - Add support to the transaction that the length is grater than 0xFFFF
   in the eSPI controller's driver.
 - Some changes according to Grant and Anton's comments.

Tested on P4080DS and MPC8536DS board.
