[PATCH v2 1/3] board: phytec: phycore-imx93: Switch to standard boot

[Primoz Fiser]

Enable standard boot for the phyCORE-i.MX93 board and use it as a new
default. Add required standard boot variables to the environment, while
removing old boot scripts and now unnecessary environment variables.
Adjust variables according to the requirements of PHYTEC ampliphy-boot
distro-boot. Last but not least, order environment vars by alphabet and
run 'make savedefconfig' to resync defconfig.

Changes in v2:
- remove bootcmd from env by not removing CONFIG_BOOTSTD_DEFAULTS and
  CONFIG_USE_BOOTCOMMAND from the defconfig
