OMAP4: fix temporary hacks that break multi-omap PM
When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4 will be true and prevent included code from building/running for OMAP2/3 as well. This problem exists in io.c where some hwmod/PM/SDRC init code is prevented from running even on OMAP2/3 when OMAP4 is included in a multi-OMAP build. A quick glance suggests that this #ifndef is no longer needed in most of the cases. In the remaining cases, the function is wrapped with "if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized out for OMAP4-only builds. Note that this is only a short-term fix. Longer-term, OMAP4 needs to create init functions for SDRC and hwmod late-init.
