ACPI: bus: Add acpi_riscv_init() function 



Add a new function for RISC-V to do architecture specific initialization
similar to acpi_arm_init(). Some of the ACPI tables are architecture
specific and there is no reason trying to find them on other
architectures. So, add acpi_riscv_init() similar to acpi_arm_init().
