target/arm/tcg: refine cache descriptions with a wrapper
This patch allows for easier manipulation of the cache description register, CCSIDR. Which is helpful for testing as well. Currently, numbers get hard-coded and might be prone to errors. Therefore, this patch adds a wrapper for different types of CPUs available in tcg to decribe caches. One function `make_ccsidr` supports two cases by carrying a parameter as FORMAT that can be LEGACY and CCIDX which determines the specification of the register. For CCSIDR register, 32 bit version follows specification [1]. Conversely, 64 bit version follows specification [2].
