The J721E DDR subsystem comprises DDR controller, DDR PHY and wrapper
logic to integrate these blocks in the device. The DDR subsystem is
used to provide an interface to external SDRAM devices which can be
utilized for storing program or data. Introduce support for the
DDR controller and DDR phy within the DDR subsystem.

Added the following registers to the DDR configuration:
- ACIOCR0,
- ACIOCR3,
- V2H_CTL_REG,
- DX8SLxDQSCTL.
Modified enable_dqs_pd and disable_dqs_pd to only touch the associated
bit fields for pullup and pulldown registers (to preserve slew rate and
other bits in that same register). Also update the dts files in the same
patch to maintain git bisectability.

The current configuration of DDR on AM654 base board is for 1600MTs but
the file name is specified as k3-am654-base-board-ddr4-1600MHz.dtsi.
Since 1600MHz is misleading, rename it to
k3-am654-base-board-ddr4-1600MTs.dtsi

U-Boot cleans and invalidate L1 and L2 caches before jumping to Linux
by set/way in cleanup_before_linux(). Additionally there is a custom
hook provided to clean and invalidate L3 cache.
Unfortunately on K3 devices(having a coherent architecture), there is no
easy way to quickly clean all the cache lines for L3. The entire address
range needs to be cleaned and invalidated by Virtual Address. This can
be implemented using the L3 custom hook but it take lot of time to clean
the entire address range. In the interest of boot time this might not be
a viable solution.
The best hit is to make sure the loaded Linux image is flushed so that
the entire image is written to DDR from L3. When Linux starts running with
caches disabled the full image is available from DDR.

Add Support for UFS Host Controller Interface (UFSHCI) for communicating
with Universal Flash Storage (UFS) devices. The steps to initialize the
host controller interface are the following:
- Initiate the Host Controller Initialization process by writing to the
Host controller enable register.
- Configure the Host Controller base address registers by allocating a
host memory space and related data structures.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
Also register this host controller as a SCSI host controller.

Correct the name of the define used CONFIG_IS_ENABLED which is
not aligned with Kconfig name: CONFIG_$(SPL_)PINCONF_RECURSIVE.
The recursive calls is conditional only for UCLASS_PINCONFIG
"pinconfig" driver.
It is always needed to call pinctrl_post_bind for UCLASS_PINCTRL
"pinctrl", the test CONFIG_IS_ENABLED(PINCONF_RECURSIVE) need to
be removed for this driver.
This correct a regression introduced because the same patch is
applied twice times in u-boot-dm branch:
