All low-level PM/SMP code using virt_to_phys() should actually use
__pa_symbol() against kernel symbols. Update code where relevant to move
away from virt_to_phys().

The device tree boot is now feature-complete and fully working,
so remove all the RealView board files. Move the remaining
realview_cpu_die() function frome "core.h" to the new "hotplug.h"
and leave just a minimal device tree core.

This newly added code missed the global fixup by commit 75305275a721
("ARM: use const and __initconst for smp_operations"). So fix it now.
Also, add missing "static" qualifier.

This adds an SMP boot method for the ARM RealView reference
designs. We also select HAVE_SMP by default and make it use
SMP_ON_UP so we only need to support one single kernel across
the RealView reference designs when using DT.
The RealViews need to have the SCU (Snoop Control Unit)
activated on boot, and this is now done by looking up its
address from the device tree and initializing it and counting
the available cores.
The RealViews boot by using a magic address register in the
system controller (SYS_FLAGS) to store the boot address,
the ROM will then read this register to the PC when the CPUs
are taken out of WFI. This code uses a handle to the syscon
regmap to access this register.
