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
