ARM: OMAP4+: Reset CPU1 properly for kexec

Browse source

We need to reset CPU1 properly for kexec when booting different
kernel versions. Otherwise CPU1 will attempt to boot the the
previous kernel's start_secondary(). Note that the restctrl
register is different from the low-power mode wakeup register
CPU1_WAKEUP_NS_PA_ADDR. We need to configure both.

Let's fix the issue by defining SoC specific data to initialize
things in a more generic way. And let's also standardize omap-smp.c
to use soc_is instead of cpu_is while at it.
