amba_register_dummy_clk() is called only once from acpi_amba_init()
and acpi_amba_init() itself is called once during the initialisation.
amba_dummy_clk can't be initialised before this in any other code
path and hence the check for already registered amba_dummy_clk is
not necessary. Drop the same.

Add support for the cpu debug devices in a new platform driver, which can
then be used on ACPI based platforms. This change would now allow runtime
power management for ACPI based systems. The driver would try to enable
the APB clock if available. But first this renames and then refactors
debug_probe() and debug_remove(), making sure they can be used both for
platform and AMBA drivers.

Currently the ACPI code doesn't bump the reference count of
the firmware node, while OF counter part does. Not that it's
a problem right now, since ACPI doesn't really use the reference
counting for firmware nodes, it still makes sense to make code
robust against any changes done there. For this,
- switch ACPI case to use device_set_node() to be unified with OF
- move reference counting to amba_device_add()
- switch to use firmware nodes instead of OF ones
In the result we will have reference counting done in the same module
for all callers independently on the nature of firmware node behind.

Commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific
initialisation into acpi_arm_init()") moved all of the ARM-specific
initialization into acpi_arm_init(). However, acpi_amba.c being outside
of drivers/acpi/arm64 got ignored and hence acpi_amba_init() was not
moved into acpi_arm_init().
Move the AMBA platform bus support into arm64 specific folder and make
acpi_amba_init() part of acpi_arm_init().
