[PATCH 4/6] ARM: imx: rework mx27_pm_init() call

[Arnd Bergmann <arnd@arndb.de>]

mx27_pm_init() uses its own initcall, unlike all of the other
functions like it. Replacing the initcall with a .init_late()
callback makes imx27 more like the others and lets us remove
the last caller of cpu_is_mx27().
