[U-Boot] [PATCH v6 1/4] dm: spi: Convert Freescale ESPI driver to driver model

[U-Boot] [PATCH v6 1/4] dm: spi: Convert Freescale ESPI driver to driver model

[Xiaowei Bao]

From: Chuanhua Han <chuanhua.han@nxp.com>

Modify the Freescale ESPI driver to support the driver model.
Also resolved the following problems:

===================== WARNING ======================
This board does not use CONFIG_DM_SPI. Please update
the board before v2019.04 for no dm conversion
and v2019.07 for partially dm converted drivers.
Failure to update can lead to driver/board removal
See doc/driver-model/MIGRATION.txt for more info.
====================================================
===================== WARNING ======================
This board does not use CONFIG_DM_SPI_FLASH. Please update
the board to use CONFIG_SPI_FLASH before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================

depends on: https://patchwork.ozlabs.org/cover/1146494/ 
Changes in v6:
	- Change #ifndef CONFIG_DM_SPI to #if !CONFIG_IS_ENABLED(DM_SPI).
Changes in v5:
	- Modify the function spi_cs_activate to fsl_spi_cs_activate.
	- Move cs to the parameter of the fsl_spi_cs_activate function.
Changes in v4:
	- Update copyright information.
	- Move the fsl_espi_platdata data structure to the 
include/dm/platform_data/.
	- Merge the contents of the fsl_espi_priv structure into 
the fsl_spi_slave structure.
	- Implement the fsl_espi_set_speed function.
	- Implement the fsl_espi_set_mode function.
	- Implement the espi_release_bus function.
	- Remove unwanted fsl_espi_bind functions.
	- Implement the fsl_espi_child_pre_probe function as needed.
	- Use #if CONFIG_IS_ENABLED(OF_CONTROL) && !CONFIG_IS_ENABLED(OF_PLATDATA).
Changes in v3:
	- Add a cover-letter for this patch set.
Changes in v2: 
	- The fsl_espi driver support both OF_CONTROL and PLATDATA.
