regmap: Correct comparison in regmap_cached 



[ Upstream commit 71df179363a5a733a8932e9afb869760d7559383 ]

The cache pointer points to the actual memory used by the cache, as the
comparison here is looking for the type of the cache it should check
against cache_type.

Fixes: 1ea975cf ("regmap: Add a function to check if a regmap register is cached")
