The following missed to add a jump to board_init_lowlevel_return for the
phycard pca100 board:

|     ARM boards: Use _text rather than TEXT_BASE
|
|     With compressed image support TEXT_BASE will become the base
|     address of the uncompressed image. What the boards want instead
|     is the base address of the decompressor code or, if not compressed,
|     the base address of the uncompressed image. Use _text which is
|     the correct one for both cases.

This fixes it by adding the jump. Also imx_nand_load_image is directly
called from lowlevel_init.S which fixes compilation with pbl support
enabled.

Tested with both compression enabled and disabled.
