ACPI: RISC-V: Implement function to reorder irqchip probe entries

On RISC-V platforms, the RINTC structures should be probed before any
other interrupt controller structures and IMSIC before APLIC. This order
is established by using MADT sub table types which are ordered in the
incremental order from the RINTC. So, add the architecture function for
RISC-V to reorder the interrupt controller probing as per the hierarchy
like below.

  ACPI_MADT_TYPE_RINTC = 24,
  ACPI_MADT_TYPE_IMSIC = 25,
  ACPI_MADT_TYPE_APLIC = 26,
  ACPI_MADT_TYPE_PLIC = 27

This means processing all RINTC structures (in the order of appearance
in MADT), followed by IMSIC strucutre and then all APLIC/PLIC
structures.
