3c1057c548 stm32mp: use device sequence number in boot_instance variable
Use the device sequence number in boot_instance variable
and no more the SDMMC instance provided by ROM code/TF-A.

After this patch we don't need to define the mmc alias in
device tree, for example:
  mmc0 = &sdmmc1;
  mmc1 = &sdmmc2;
  mmc2 = &sdmmc3;
to have a correct mapping between the ROM code boot device =
"${boot_device}${boot_instance}" and the MMC device in U-Boot.

With this patch the 'mmc0' device (used in mmc commands) is
always used when only one instance sdmmc is activated in device
tree, even if it is only the sdmmc2 or sdmmc3.

7ae22d7278 arm: stm32mp: bsec: add permanent lock support in bsec driver
Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver.
The write access only available for Trusted boot mode, based on new
SMC STM32_SMC_WRLOCK_OTP.

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

Read lock status of fuse 57 (0x39)

  STM32MP> fuse sense 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

Set permanent lock of fuse 57 (0x39)

  STM32MP> fuse prog 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

WARNING: the OTP lock is updated only after reboot

WARING: Programming lock or fuses is an irreversible operation!
        This may brick your system.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.
