With CONFIG_MMU_EARLY enabled the board does not survive the call
to imx53_init_lowlevel(). This should not happen, but the reasons
are currently unknown. This works on other boards like the i.MX53
QSB.
This patch moves the call to imx53_init_lowlevel to
barebox_arm_reset_vector() which is executed with MMU disabled.
