[PATCH v3 0/7] refactor spi_mpc8xxx.c and add eSPI controller support

[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.

Tested on P4080DS and MPC8536DS board based on latest Linux tree.

v3 main changes:
 - Update to the latest kernel base.
 - Change the file spi_mpc8xxx.c to spi_fsl_fsl.c verbatim.
 - Add the SPI flash partition code to the m25p80 probe function.
 - Add a quirks for SPI master to handle the contrains of the controller.
