Simplify the DT parsing by removing the parsing of the nvmem layout node
with "st,stm32-nvmem-layout" compatible.
The expected OTP NAME can directly be found in a sub-node named
NAME@ADDRESS of the BSEC node, the NVMEM provider node.
This patch also removes this specific binding introduced for TF-A.

The "ngpios" property is deprecated and may be removed.
Use the "gpio-ranges" property where the last parameter of that

Use dt_find_otp_name() to retrieve platform OTP information
from device tree, directly or through stm32_get_otp_index() and
stm32_get_otp_value() platform services.
String definitions replace hard-coded values, they are used to call
this new function.

Avoid parsing device tree every time when returning
the DDR size.
A cache flush on this size is also added because TZC400 configuration
is applied at the end of BL2 after MMU and data cache being turned off.
Configuration needs to retrieve the DDR size to generate the correct
region. Access to the size fails because the value is still in the data
cache. Flushing the size is mandatory.

Device Tree address is now a parameter for dt_open_and_check() function.
This will allow better flexibility when introducing PIE and FIP.
The fdt pointer is now only assigned if the given address holds
a valid device tree file. This allows removing the fdt_checked variable,
as we now check fdt is not null.

New helper functions to get GPIO banks configuration from the FDT.
stm32_get_gpio_bank_pinctrl_node() allows stm32mp platforms to
differentiate specific GPIO banks when these are defined with a specific
path in the FDT.
fdt_get_gpio_bank_pin_count() returns the number of pins in a GPIO bank
as it depends on the SoC variant.

The STM32 platform port parse DT nodes to find base address to
peripherals. It does this by using its own implementation, even though
this functionality is generic and actually widely useful outside of the
STM32 code.
Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

The STM32 platform code uses its own set of FDT helper functions,
although some of them are fairly generic.
Remove the implementation of fdt_read_uint32_default() and implement it
on top of the newly introduced fdt_read_uint32() function, then convert
all users over.
This also fixes two callers, which were slightly abusing the "default"
semantic.

The device tree parsing code for the STM32 platform is using its own FDT
helper functions, some of them being rather generic.
In particular the existing fdt_read_uint32_array() implementation is now
almost identical to the new generic code in fdt_wrappers.c, so we can
remove the ST specific version and adjust the existing callers.
Compared to the original ST implementation the new version takes a
pointer to the DTB as the first argument, and also swaps the order of
the number of cells and the pointer.

The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.
Device tree files are also updated to manage vdd-supply regulator.
