ACPI: Rename acpi_processor_hotadd_init and remove pre-processor guards

acpi_processor_hotadd_init() will make a CPU present by mapping it
based on its hardware id.

'hotadd_init' is ambiguous once there are two different behaviours
for cpu hotplug. This is for toggling the _STA present bit. Subsequent
patches will add support for toggling the _STA enabled bit, named
acpi_processor_make_enabled().

Rename it acpi_processor_make_present() to make it clear this is
for CPUs that were not previously present.

Expose the function prototypes it uses to allow the preprocessor
guards to be removed. The IS_ENABLED() check will let the compiler
dead-code elimination pass remove this if it isn't going to be
used.
