Tony Dinh 54a08c4139 ddr: marvell: a38x: Add support for DDR4 from Marvell mv-ddr-marvell repository
This syncs drivers/ddr/marvell/a38x/ with the master branch of repository
https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git

up to the commit "mv_ddr: a3700: Use the right size for memset to not overflow"
d5acc10c287e40cc2feeb28710b92e45c93c702c

This patch was created by following steps:

	1. Replace all a38x files in U-Boot tree by files from upstream github
	Marvell mv-ddr-marvell repository.

	2. Run following command to omit portions not relevant for a38x, ddr3, and ddr4:

	files=drivers/ddr/marvell/a38x/*
	unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_APN806 \
		-UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
		-UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \
		-UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DCONFIG_ARMADA_38X -UCONFIG_ARMADA_39X \
		-UCONFIG_64BIT $files

	3. Manually change license to SPDX-License-Identifier
	(upstream license in  upstream github repository contains long license
	texts and U-Boot is using just SPDX-License-Identifier.

After applying this patch, a38x, ddr3, and ddr4 code in upstream Marvell github
repository and in U-Boot would be fully identical. So in future applying
above steps could be used to sync code again.

The only change in this patch are:
	1. Some fixes with include files.
	2. Some function return and basic type defines changes in
	mv_ddr_plat.c (to correct Marvell bug).
	3. Remove of dead code in newly copied files (as a result of the
	filter script stripping out everything other than a38x, dd3, and ddr4).
