Add cpufreq driver based on ACPI CPPC for RISC-V. The driver uses either
SBI CPPC interfaces or the CSRs to access the CPPC registers as defined
by the RISC-V FFH spec.

RISC-V: ACPI: Update the return value of acpi_get_rhct()2023-10-26T16:40:32ZSunil V L2023-10-18T12:40:05Zurn:sha1:a06835227280436c1aae021a3f43d3abfcba3835
acpi_get_rhct() currently returns pointer to acpi_table_header
structure. But since this is specific to RHCT, return pointer to
acpi_table_rhct structure itself.

RHCT is a new table defined for RISC-V to communicate the
features of the CPU to the OS. Create a new architecture folder
in drivers/acpi and add RHCT parsing code.
