As the PHYTEC phyCORE-i.MX91 [1] is just another variant of the existing
PHYTEC phyCORE-i.MX93 SoM but with i.MX91 SoC populated instead, add it
to the existing board-code "phycore_imx93", and rename that board to
"phycore_imx91_93" to reflect the dual SoCs support. While at it, also
rename and change common files accordingly. This way i.MX91 and i.MX93
SoC variants of the phyCORE SoM share most of the code and documentation
without duplication, while maintaining own device-tree and defconfigs
for each CPU variant.

Supported features:
 - 1GB LPDDR4 RAM
 - Debug UART
 - EEPROM
 - eMMC
 - Ethernet
 - SD-card
 - USB

CFG_WITH_SOFTWARE_PRNG=y was added as an OPTEE argument to workaround
some bugs related to TRNG which have been fixed now[1]. Therefore this
patch drops the redundant argument from the documentation.

Commit 488445cefa1 ("doc: Move FIT into its own directory") moved the
documentation in doc/uImage.FIT to doc/usage/fit, subsequently all
documents and example sources have been converted to reStructuredText.

Fix (almost) all of the remaining occurrences of the old path and
filenames across the tree.

The exception is doc/uImage.FIT/command_syntax_extensions.txt which
apparently has been removed entirely, or at least I was unable to
locate where that document is now.

- Add support for i.MX952.
- Add support for XPI1 on imx943_evk.

U-Boot produces flash.bin as the final boot image when building for
the i.MX95 EVK, but the documentation refers to imx-boot-imx95.bin.

Update the instructions to use flash.bin when copying the image to
the SD card.

The imx-oei and imx-sm build systems defaults to:

  TC_VERSION ?= 14.2.rel1

but the documentation still instructs users to download the 13.3 toolchain.
This causes the build to fail because the expected directory name does
not exist.

Update the documentation to reference the 14.2 toolchain to match the build
system default.
