[U-Boot] [PATCH 1/2] config_distro_bootcmd.h: Allow user to indicate that usb is inited in preboot

When using usb-keyboard support, typically usb will already get started from
preboot. In this case doing it again in the bootcmd is undesirable.

Allow the user of config_distro_bootcmd to indicate that usb is inited in
preboot through the user setting BOOTENV_PREBOOT_INITS_USB.
