helios64: u-boot: cherry-pick fdt_fixup_ethernet logs and fileenv cmd
Pull two generic v2026.04 patches that helios64 currently misses because BOOTPATCHDIR points at the self-contained board_helios64 subdirectory and does not inherit from patch/u-boot/v2026.04/. - 1001-fdt_fixup_ethernet-add-logs.patch: diagnostic log_info() calls in boot/fdt_support.c and boot/image-fdt.c. helios64 hits this path via its gmac ethernet fixups. - cmd-fileenv-read-string-from-file-into-env.patch: adds the 'fileenv' command. Enable CONFIG_CMD_FILEENV in helios64.conf alongside, matching the convention of odroidm1 / khadas-vim3 / odroidm1s which bring in the patch and enable the option in the same commit. The command is purely additive — it does not affect armbianEnv.txt or the existing env mechanics, only adds a new CLI command to read a file into env. Other parent-level patches (rk3288 VOP, rk3588 I2S MCLK, DW-HDMI disable) are SoC-specific or require config options helios64 does not enable, so they are not pulled in.
