[U-Boot] [PATCH v2] mpc512x: Add display of reset status register

[Detlev Zundel]

Content of the RSR is put into gd early so we can output it together
with the CPU info.  The clearing of gd in board_init_f is redundant for
this architecture as it is done in cpu_init_f so we remove it.

Changes from v1:

- Keep conditional expressions sorted
