powerpc/85xx: Fix SRIO LAW setup on corenet_ds boards
In function board_early_init_r(), serdes will not be initialize yet.
Thus sRIO was always considered disabled. Move the check for sRIO into
misc_init_r() which is called after fsl_serdes_init().
Also, fixed warning associated with gur variable possibly not being
used.
