arm: Move modules shared with arm64 into arch/arm-common
This helps understanding which source modules are shared between arm and
the upcoming arm64 architecture. If leaving them in arch/arm, the risk
is that changes to arm miss the interdependency with arm64.
We may want to do the same for common asm headers in the future.

arm: Factor out common control.c module
Many functions will be shared with arm64.
This creates one new inter-module interface: arm_cpu_reset. It now takes
the desires PC after reset as parameter, instead of overwriting the
related register if cpu_on_entry is not the final value.

arm64: add sysregs helper macros
On the AArch32 port of Jailhouse, the arm_write_sysreg and
arm_read_sysreg macros are used to access the system registers.
Implementing these helpers on AArch64 allows to approach some low
hanging fruit when looking for code to reuse from the AArch32 port.
On AArch64 we always get a u64 value from a system register, while
on AArch32 it might be either u32 or u64. We need to look at the
users of this macro on a case by case basis and see if it makes
sense to reuse code.

arm64: add definitions for the AArch64 page table format
The AArch64 page table format is very similar, almost identical to
the AArch32 page table format. Add a header file for the AArch64 page
table format, based on the AArch32 implementation.
AArch64 introduces an extra level of page tables, for a total of
four, and support for different translation granule sizes.
Sticking to a granule size of 4Kb, we end up with an identical page
table format to AArch32. Using either 3 or the full 4 supported
levels of page tables, we can reach a physical address range of
48 bits.

arm64: plug the irqchip and GICv2 code from AArch32
We plug the irqchip handling code, and the GICv2 implementation from
AArch32. arch_handle_sgi and arch_handle_phys_irq are only provided as
stubs because they will be replaced with the arm-common versions soon.
GICv3 is slightly trickier; it makes heavier use of the sysregs, so
we will need to review more carefully that the sysregs macros do
the right thing.

arm64: PSCI support for SMP on AArch64
On AArch64 we pretty much rely on PSCI being present for SMP
support (turning multiple cores on and off). This patch implements
the helpers needed for SMP and plugs in the PSCI code from AArch32.
On AArch64 PSCI calls can be issued via SMC64 as well, contrary to
AArch32 which uses SMC32 calls only. We add the changes necessary to
support the requests that are used by a Linux root cell. CPU hotplug now
is still working after we enable Jailhouse.
