RISC-V: Add support to build the ACPI core
Enable ACPI core for RISC-V after adding architecture-specific
interfaces and header files required to build the ACPI core.
1) Couple of header files are required unconditionally by the ACPI
core. Add empty acenv.h and cpu.h header files.
2) If CONFIG_PCI is enabled, a few PCI related interfaces need to
be provided by the architecture. Define dummy interfaces for now
so that build succeeds. Actual implementation will be added when
PCI support is added for ACPI along with external interrupt
controller support.
3) A few globals and memory mapping related functions specific
to the architecture need to be provided.
