Adds initial low power suspend functionality to MX51.
Supports "mem" and "standby" modes.

+static int __init mx5_pm_init(void)
+{
+	if (gpc_dvfs_clk == NULL)
+		gpc_dvfs_clk = clk_get(NULL, "gpc_dvfs");
+
+	if (!IS_ERR(gpc_dvfs_clk)) {
+		if (cpu_is_mx51())
+			suspend_set_ops(&mx5_suspend_ops);
+	} else {
+		printk(KERN_ERR "Cannot enter SRPG suspend -no gpc_dvfs clock!\n");
+		return -EPERM;

This will print a warning on every non i.MX51 machine, not a good idea.
Please just bail out early on irrelevant machines.
