RISC-V: Add ACPI initialization in setup_arch()
Initialize the ACPI core for RISC-V during boot.
ACPI tables and interpreter are initialized based on
the information passed from the firmware and the value of
the kernel parameter 'acpi'.
With ACPI support added for RISC-V, the kernel parameter 'acpi'
is also supported on RISC-V. Hence, update the documentation.
