Print newline after hex address in aarch64 el3_panic function
Make the aarch64's el3_panic() function print a newline character after
PC address, otherwise the output can get mangled in one line with output
from other firmware. Here is an example of how the output of el3_panic()
got mangled with Linux' console output:
ERROR: Unhandled External Abort received on 0x80000001 at EL3!
ERROR: exception reason=1 syndrome=0x92000210
PANIC at PC : 0x0000000004027400[13438.473133] rcu: INFO: rcu_sched detected stalls on CPUs/tasks:
[13438.479255] rcu: 1-...0: (4 ticks this GP) idle=35e/1/0x4000000000000000 softirq=146459/146459 fqs=2625
The aarch32 version of this function already does this.
