ARM: OMAP2+: Remove legacy PM init
This is no longer needed when booted with device tree. And let's replace cpu_is with soc_is for the PM code to avoid confusion, they do the same thing. Note that omap_pmic_late_init() now just calls omap3_twl_init() and omap4_twl_init() to initialize the voltage layer so we can remove the remaining references to twl-common code and remove it in the following patch.
