ARM: OMAP2+: Fix booting for am335x after moving to simple-pm-bus

We now depend on SIMPLE_PM_BUS for probing devices. While we have it
selected in omap2plus_defconfig, custom configs can fail if it's missing.

As SIMPLE_PM_BUS depends on OF and PM, we must now select PM in Kconfig.
We have already OF selected by ARCH_MULTIPLATFORM.

Let's also drop the earlier PM dependency entries as suggested by
Geert Uytterhoeven <geert@linux-m68k.org>.
