[PATCH] ARM: OMAP5+: Reuse OMAP4 PM code for OMAP5 and DRA7

[Nishanth Menon]

OMAP4, OMAP5 and DRA7 share a lot of common logic and data structures.
These have been enabled in the previous patches, however, this also
means that OMAP5 or DRA7 only builds also need to build OMAP4 logic.
Update to reuse OMAP4 logic.

This fixes the 'undefined reference to 'omap4_pm_init_early'' in
OMAP5 or DRA7 only builds.

Fixes: 6af16a1dac5465c ("ARM: DRA7: Add hook in SoC initcalls to enable pm initialization")
Fixes: 628ed4717000789 ("ARM: OMAP5: Add hook in SoC initcalls to enable pm initialization")
Reported-by: Tony Lindgren <tony at atomide.com>
Signed-off-by: Nishanth Menon <nm at ti.com>
---

This fixes the regression with randconfig that Tony reported with
omap-for-v3.18/soc branch.

Tested with CONFIG_ARCH_OMAP2, CONFIG_ARCH_OMAP3, CONFIG_ARCH_OMAP4,
CONFIG_SOC_OMAP5, CONFIG_SOC_AM33XX, CONFIG_SOC_AM43XX, CONFIG_SOC_DRA7XX
only builds.
