Make sure value in register r0 and r1 is preserved and passed to
the board_init_ll() and mxs_common_spl_init() where it can be
processed further. The value in r0 can be configured during the
BootStream generation to arbitary value, r1 contains pointer to
return value from CALL'd function.
This patch also clears the value in r0 before returning to BootROM
to make sure the BootROM is not confused by this value.
Finally, this patch cleans up some comments in the start.S file.

Some MXS based boards do not implement the card-detect signal. Allow
user to specify alternate card-detect implementation.

The DRAM initialization, after SPL has complete, is exactly the same
for all mxs SoCs so we should name it accordinly.
The following boards has been changed:
* apx4devkit
* m28evk
* mx28evk
* sc_sps_1

The sys_proto.h functions (except the boot modes) are compatible with
i.MX233 and i.MX28 so we use 'mxs' prefix for its methods.

This adds support for Bluegiga APX4 Development Kit. It is built around
Freescale i.MX28. Currently supported features are: ethernet, I2C, MMC,
RTC and USB. APX4 has only one ethernet port.
