Enable DRAM ASR, auto self-refresh, conditionally, based on DT PWRCTL
register bits. While ASR does save considerable amount of power at
runtime automatically, it also causes LTDC underruns on large panels.
Let user select whether or not ASR is required or not, generally ASR
should be enabled on portable and battery operated devices.

The k3-ddrss driver wants to configure the DDRSS_V2A_CTL_REG to reflect
the maximum possible SDRAM of 2 GB for AM64x (instead of the register's
default that says 8 GB, which the AM64x DDR controller wouldn't support).
The offset 0x20 was correct, but the register name DDRSS_V2A_R1_MAT_REG
was that of the next register at offset 0x24.

Introduce ECC Functionality for full memory space as implemented in the
DDRSS. The following is done to accomplish this:
* Introduce a memory region "ss" to allow dt to provide DDRSS region,
which is not the same as "ctl" which is the controller region.
* Introduce a "ti,ecc-enable" flag which allows a memorycontroller
instance to enable ecc.
* Introduce functionality to properly program the DDRSS registers to
enable ECC for the full DDR memory space if enabled with above flag.
* Expose a k3_ddrss_ddr_fdt_fixup call to allow fixup of fdt blob to
account from DDR memory that must be reserved for ECC operation.

The current address being read from dt actually represents the ddrss_ctl

The support of a predefined DDR PHY tuning result is removed for
STM32MP1 driver because it is not needed at the supported frequency
when built-in calibration is executed.
The calibration parameters were provided in the device tree by the
optional node "st,phy-cal", activated in ddr helper file by the
compilation flag DDR_PHY_CAL_SKIP and filled with values generated
by the CubeMX DDR utilities.
This patch
- updates the binding file to remove "st,phy-cal" support
- updates the device trees and remove the associated defines
- simplifies the STM32MP1 DDR driver and remove the support of
the optional parameter "st,phy-cal"
After this patch, the built-in calibration is always executed
and the calibration registers are moved in the phy dynamic part;
that allows manual tests.
