ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3
The USB boot without the stand-by MPU is available on ES3 or later of LD11 SoC, but the code in this if-conditional block must not be run when booting from USB. Check if the boot device is USB, and skip the code in the case. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
