memory_bus: Add infrastructure for per-bus probing
All the probing functions for the traditional memory-mapped chips,
parallel, LPC and FWH, are parameterized by additional chip proper-
ties like the chip size and feature bits like FEATURE_ADDR_SHIFTED.
Hence, we match against an extended `id_info' with chip size and
feature bits. For a match, all the feature bits assumed during
probing, need to be set for a given chip as well.
