Add cacheinfo support for OpenRISC. Currently, a few CPU cache attributes pertaining to OpenRISC processors are exposed along with other unrelated CPU attributes in the procfs file system (/proc/cpuinfo). However, a few cache attributes remain unexposed. Provide a mechanism that the generic cacheinfo infrastructure can employ to expose these attributes via the sysfs file system. These attributes can then be exposed in /sys/devices/system/cpu/cpuX/cache/indexN. Move the implementation to pull cache attributes from the processor's registers from arch/openrisc/kernel/setup.c with a few modifications. This implementation is based on similar work done for MIPS and LoongArch.
