When CONFIG_PM is disabled, we get a build error:

arch/arm/mach-omap2/omap-smp.c: In function 'omap4_smp_maybe_reset_cpu1':
arch/arm/mach-omap2/omap-smp.c:309:20: error: implicit declaration of function 'omap4_get_cpu1_ns_pa_addr'; did you mean 'omap4_get_scu_base'? [-Werror=implicit-function-declaration]

We need to fix this in multiple files, to ensure the declaration is visible,
to actually build the function without CONFIG_PM, and to only call it
when OMAP4 and/or OMAP5 are enabled.

Fixes: 351b7c49 ("ARM: omap2+: Revert omap-smp.c changes resetting CPU1 during boot")
