ARM: 9160/1: NOMMU: Reload __secondary_data after PROCINFO_INITFUNC

ARM: 9160/1: NOMMU: Reload __secondary_data after PROCINFO_INITFUNC

[ Upstream commit 7202216a6f34d571a22274e729f841256bf8b1ef ]

__secondary_data used to reside in r7 around call to
PROCINFO_INITFUNC. After commit 95731b8ee63e ("ARM: 9059/1: cache-v7:
get rid of mini-stack") r7 is used as a scratch register, so we have
to reload __secondary_data before we setup the stack pointer.
