This patch remove the default preboot command 'usb start' for STMicroelectronics board. These command is added by the commit 324d77998ed6 ("Define default CONFIG_PREBOOT with right config option")' and commit 44758771eefb ("arm: move CONFIG_PREBOOT="usb start" to KConfig").
The USB storage boot (not activated in stm32mp1.h) is correctly managed by distro boot command 'usb_boot' (defined in include/config_distro_bootcmd.h, it include 'usb start') and USB keyboard is not supported in stm32mp15 defconfig.
So this patch avoids unnecessary USB initialization which slows down the start-up: starting USB... Bus usbh-ehci@5800d000: USB EHCI 1.00 scanning bus usbh-ehci@5800d000 for devices... 3 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found

In this case you should disable CONFIG_USE_PREBOOT.
