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

__secondary_data used to reside in r7 around call to
PROCINFO_INITFUNC. After commit 95731b8ee6 ("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.

Fixes: 95731b8ee6 ("ARM: 9059/1: cache-v7: get rid of mini-stack")
