[PATCH v2 4/7] hw/acpi/Kconfig: Add missing dependencies to ACPI_PIIX4

[Bernhard Beschow]

piix4_pm_realize() uses apm_init() and pm_smbus_init(), so both APM and
ACPI_SMBUS are provided by the device model managed by ACPI_PIIX4.

The ACPIREGS are also provided by ACPI_PIIX4, so needs to select ACPI.
