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.

The second UART is used on the mba53 baseboard. The first UART is only
used on custom hardware. This patch changes the UART to the one used
on the freely available baseboard.

This means using an uint64_t instead of a struct pad_desc which allows
us to change pad settings using logic operations. Also with this we
can more easily keep the iomux tables in sync with the kernel.
