spi/mpc8xxx: refactor the common code for SPI/eSPI controller
Refactor the common code in file spi_fsl_spi.c to spi_fsl_lib.c used by SPI/eSPI controller driver as a library, and leave the QE/CPM SPI controller code in the SPI controller driver spi_fsl_spi.c. Because the register map of the SPI controller and eSPI controller is so different, also leave the code operated the register to the driver code, not the common code.

This enables using the Freescale SPI controllers in master mode.
MPC83xx platform uses the controller in cpu mode or CPM/QE mode.
