Having saved environments usually causes inconsistencies while in
development workflow. The saved environments conflict with the
default ones that U-boot should be updating during development
but that doesn't happen and the saved environments need to be
reset during bootups to test the changes causing extra debugs.
Remove the saved environments as a default. Environments can always
be re-enabled locally if one does like them or needs them for
some production environment. Optionally, Uenv.txt can also be used on
some of the boot media.

By providing entries in the binman node of the device tree, binman will
be able to find and package board config artifacts generated by
TIBoardConfig with sysfw.bin and generate the final image sysfw.itb.
It will also pick out the R5 SPL and sign it with the help of TI signing
entry and generate the final tiboot3.bin.
Entries for A72 build have been added to k3-j721e-binman.dtsi to
generate tispl.bin and u-boot.img.
Support has been added for both HS-SE(SR 1.1), HS-FS(SR 2.0) and GP images
In HS-SE, the encrypted system firmware binary must be signed along with
the signed certificate binary.
HS-SE:
* tiboot3-j721e_sr1_1-hs-evm.bin
* sysfw-j721e_sr1_1-hs-evm.itb
* tispl.bin
* u-boot.img
HS-FS:
* tiboot3-j721e_sr2-hs-fs-evm.bin
* sysfw-j721e_sr2-hs-fs-evm.itb
* tispl.bin
* u-boot.img
GP:
* tiboot3.bin -->tiboot3-j721e-gp-evm.bin
* sysfw.itb --> sysfw-j721e-gp-evm.itb
* tispl.bin_unsigned
* u-boot.img_unsigned
It is to be noted that the bootflow followed by J721E requires:
tiboot3.bin:
* R5 SPL
* R5 SPL dtbs
sysfw.itb:
* TIFS
* board-cfg
* pm-cfg
* sec-cfg
* rm-cfg
tispl.bin:
* DM
* ATF
* OP-TEE
* A72 SPL
* A72 SPL dtbs
