Shiji Yang 6951526792 uboot-mediatek: update to U-Boot release v2024.07
1. Rename function _do_env_set() to env_do_env_set().
2. Replace kwbimage hack with UBOOT_CUSTOMIZE_CONFIG:
   "--disable TOOLS_KWBIMAGE" and "--disable TOOLS_LIBCRYPTO".
3. Disable CONFIG_CMD_BOOTEFI_BOOTMGR for all supported devices
   because the newly added UEFI bootmenu entries doesn't work.
4. Enable CONFIG_VERSION_VARIABLE for the OpenWrt One.

Subject: [PATCH 44/71] cmd: mtd: add markbad subcommand for NMBM testing
This patch adds:
* Mark bad block on lower mtd device and erase on upper mtd
device, which will trigger remapping:
$ mtd markbad spi-nand0 0x20000 (mark block1 as bad)
$ mtd erase nmbm0 0x20000 0x20000 (let nmbm detect the bad block and remap it)
* Clear bad block mark through:
$ mtd erase.dontskipbad spi-nand0 0x20000 0x20000
(After cleaning bad block mark, we need to rebuild nmbm manage table.)
