[PATCH v1 2/4] accel/tcg: remove link between guest ram and TCG cache size

[Alex Bennée]

Basing the TB cache size on the ram_size was always a little heuristic
and was broken by a1b18df9a4 which caused ram_size not to be fully
realised at the time we initialise the TCG translation cache.

The current DEFAULT_CODE_GEN_BUFFER_SIZE may still be a little small
but follow-up patches will address that.
