suspend: constify platform_suspend_ops

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849).

Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.
