At the moment, we don't have a common API for working with
SM, only the smc_call() function. This approach is not generic
and difficult to configure and maintain.
This patch adds UCLASS_SM with the generic API:
- sm_call()
- sm_call_write()
- sm_call_read()
These functions operate with struct pt_regs, which describes
Secure Monitor arguments.

- Assorted TI K3 updates, use ".dtso" for device tree overlays to match
general usage, mkimage fixes/improvements, assorted platform
updates/fixes, other assorted driver/platform fixes.
All K3 boards now are secure by default, instead of setting this in each
defconfig, make it implied by the ARCH config.
The only exception is IOT2050, which I do not believe will have any
problems with being a TI_SECURE_DEVICE, but for now turn it off to keep
its config the same.

As the code to switch an ARM core from secure to the non-secure state
needs to know the base address of the Generic Interrupt Controller
(GIC), we read an Arm Cortex defined system register that is supposed to
hold that base address. However there are SoCs out there that get this
wrong, and this CBAR register either reads as 0 or points to the wrong
address. To accommodate those systems, so far we use a macro defined in
some platform specific header files, for affected boards.
To simplify future extensions, replace that macro with a Kconfig variable
that holds this override address, and define a default value for SoCs
that need it.

DM_DRIVER_GET will redeclare the fs_loader driver without the correct
alignment. This causes GCC to use the default section alignment of 32
bytes. This in turn creates a gap in the linker list due to the padding
required to achieve the correct alignment, corrupting all further entries.
Use DM_DRIVER_REF instead, which doesn't redeclare anything.

The man page correctly said that -B was ignored without -E, while the
`mkimage -h` output suggested otherwise. Now that -B can actually be
used by itself, update the man page.
While at it, also amend the `mkimage -h` line to mention the
connection with -E.
The FDT header is a fixed 40 bytes, so its size cannot (and is not)
modified, while its alignment is a property of the address in RAM one
loads the FIT to, so not something mkimage can affect in any way. (In
the file itself, the header is of course at offset 0, which has all
possible alignments already.)

The ARMv8.5 architecture extension defines architectural RNDR/RNDRRS
system registers, that provide 64 bits worth of randomness on every
read. Since it's an extension, and implementing it is optional, there is
a field in the ID_AA64ISAR0_EL1 ID register to query the availability
of those registers.
Add a UCLASS_RNG driver that returns entropy via repeated reads from
those system registers, if the extension is implemented.
The driver always binds, but checks the availability in the probe()
routine.
This helps systems which suffer from low boot entropy, since U-Boot can
provide entropy via the generic UEFI entropy gathering protocol to the OS,
at an early stage.

Padding the header of an external FIT image is achieved by truncating
the existing temporary FIT file to match the required alignment before
appending image data. Reusing an existing file this way means that the
padding will likely contain a portion of the original data not
overwritten by the new header.
Zero out any data past the end of the new header, and stop at either
the end of the desired padding, or the end of the old FIT file,
whichever comes first.
