media: staging/cxd2099: convert to regmap API

Browse source

Convert the cxd2099 driver to use regmap for I2C accesses, removing all
own i2c_*() functions. With that, make the driver a proper I2C client
driver. This also adds the benefit of having a proper cleanup function
(cxd2099_remove() in this case) that takes care of resource cleanup
upon I2C client deregistration.

At this point, keep the static inline declared cxd2099_attach()
function so that drivers using the legacy/proprietary style attach way
still compile, albeit lacking the cxd2099 driver functionality. This
is taken care of in the next two patches.
