lib/cpus: fix branching in reset function for cortex-a72 AARCH32 mode

Browse source 
In AARCH32 mode, cortex_a72_reset_func branches to address in lr
register instead of r5 register. This leads to linux boot failure
of Cortex-A72 cores in AARCH32 mode on Juno-R2 board.

This patch fixes the branching of cortex_a72_reset_func to r5
register as in cortex_a57_reset_func implementation.
