ARM: OMAP4: PM: fix errata handling when CONFIG_PM=n

From: Kevin Hilman <[email protected]>

commit c9621844 (ARM: OMAP4: PM: add errata support) introduced errata handling for OMAP4, but was broken when CONFIG_PM=n.

When CONFIG_PM=n, pm44xx.c is not compiled, yet that is where pm44xx_errata is defined. However, these errata are needed for the SMP boot/hotplug case also, and are primarily used in omap-smp.c.

Move the definition of pm44xx_errata to omap-smp.c so that it's available even in the CONFIG_PM=n case.
