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.
