regmap: Drop early readability check
We have some drivers that have a use case for cached write only
registers, doing read/modify/writes on read only registers in order to
work more easily with bitfields. Go back to trying the cache before we
check if we can read from the device.
Fixes: eab5abdeb79f0 ("regmap: Check for register readability before checking cache during read")
