ARM: shmobile: smp: Enforce shmobile_smp_* alignment

Browse Source 
commit 379c590113ce46f605439d4887996c60ab8820cc upstream.

When the addresses of the shmobile_smp_mpidr, shmobile_smp_fn, and
shmobile_smp_arg variables are not multiples of 4 bytes, secondary CPU
bring-up fails:

    smp: Bringing up secondary CPUs ...
    CPU1: failed to come online
    CPU2: failed to come online
    CPU3: failed to come online
    smp: Brought up 1 node, 1 CPU

Fix this by adding the missing alignment directive.

Fixes: 4e960f52fc ("ARM: shmobile: Move shmobile_smp_{mpidr, fn, arg}[] from .text to .bss")
