ARM: shmobile: smp: Enforce shmobile_smp_* alignment
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: 4e960f52fce16a3b ("ARM: shmobile: Move shmobile_smp_{mpidr, fn, arg}[] from .text to .bss")
Closes: https://lore.kernel.org/r/CAMuHMdU=QR-JLgEHKWpsr6SbaZRc-Hz9r91JfpP8c3n2G-OjqA@mail.gmail.com
