arm64: Kconfig: Fix dependencies to enable ACPI_HOTPLUG_CPU
Both ACPI_PROCESSOR and HOTPLUG_CPU are needed by ACPI_HOTPLUG_CPU. Otherwise, we can have compiling error with the following configurations. CONFIG_HOTPLUG_CPU=n CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_HOTPLUG_CPU=y arch/arm64/kernel/smp.c: In function ‘arch_unregister_cpu’: arch/arm64/kernel/smp.c:563:9: error: implicit declaration of \ function ‘unregister_cpu’; did you mean ‘register_cpu’? \ [-Werror=implicit-function-declaration] 563 | unregister_cpu(c); | ^~~~~~~~~~~~~~ | register_cpu Fix it by enabling ACPI_HOTPLUG_CPU when both ACPI_PROCESSOR and HOTPLUG_CPU are enabled, consistent with other architectures like x86 and loongarch. Fixes: 9d0873892f4d ("arm64: Kconfig: Enable hotplug CPU on arm64 if ACPI_PROCESSOR is enabled.")
