In an effort to enable -Wcast-function-type in the top-level Makefile to support Control Flow Integrity builds, there are the need to remove all the function callback casts. The first patch creates a macro called ACPI_DECLARE_SUBTABLE_PROBE_ENTRY to initialize the acpi_probe_entry struct using the probe_subtbl field instead of the probe_table field to avoid function cast mismatches. The second patch modifies the IRQCHIP_ACPI_DECLARE macro to use the new defined macro ACPI_DECLARE_SUBTABLE_PROBE_ENTRY instead of the macro ACPI_DECLARE_PROBE_ENTRY. Also, modifies the prototype of the functions used by the invocation of the IRQCHIP_ACPI_DECLARE macro to match all the parameters.
