This adds the dirmap API originally introduced in Linux commit aa167f3 ("spi: spi-mem: Add a new API to support direct mapping"). This also includes several follow-up patches and fixes.
Changes from Linux include:
- Added Kconfig option
- Changed struct device to struct udevice
- Changed struct spi_mem to struct spi_slave
This patch is obtained from the following patch https://patchwork.ozlabs.org/project/uboot/patch/20210205043924.149504-3-sea...

Look like the following code is not part of this if construct, we need that to build only when SPI_DIRMAP is defined otherwise it footprint increase for non-DIRMAPs. Also please take care of unnecessary code while copying from Linux and add SHA1 in the commit message.
