Introduce a minimal cpuinfo structure to hold cache related info. The instruction/data cache size and cache line size are initialized early in the boot to default Kconfig values. They will be overwritten with data from PVR/dtb if the microblaze UCLASS_CPU driver is enabled. The cpuinfo struct was placed in global_data to allow the microblaze UCLASS_CPU driver to also run before relocation (initialized global data should be read-only before relocation). gd_cpuinfo() helper macro was added to avoid volatile "-Wdiscarded-qualifiers" warnings when using the pointer directly.
