[PATCH v2] board: rockchip: Fix binman_init failure on EVB-RK3568

[Jagan Teki]

For some newer SoCs like RK3568, the Rockchip has not released
any DDR drivers yet so idbloader needs to create manually using
DDR binaries offered by rkbin. This indeed no requirement to
enable TPL in the U-Boot source code.

If we mark TPL disabled and mark BINMAN enabled by default then
there would be an issue of binman_init failure during board
relocation. This is true as binman failed to find the top-level
node like u-boot-tpl here.

Here is the boot issue observed in Radxa-CM3 RK3566 board,

 U-Boot 2023.01-rc4-00057-gac2505d463-dirty (Jan 04 2023 - 23:44:18 +0530)

 Model: Radxa Compute Module 3(CM3) IO Board
 DRAM:  2 GiB
 binman_init failed:-2
 initcall sequence 000000007ffd2008 failed at call 0000000000a18cac (err=-2)
 ### ERROR ### Please RESET the board ###

This might be fixed via binman node in rockchip-u-boot.dtsi however
disable BINMAN_FDT for evb-rk3568 defconfig for now as we are at the
end of the release cycle.

for ARM64 boards")
