The VCNL4040 is almost identical to the VCNL4200 as far as register
layout goes but just need to check a different ID register location.

This does change the initialization sequence of the VCNL4200 to use word writes
instead of byte writes. The VCNL4200 says that word read and writes should be
used to access the registers but I don't have a 4200 to test with. The VCNL4040
doesn't initialize properly with the byte writes.

Before returning measured temperature data to upper layer we need to
make sure that the reading was marked as "valid" to avoid reporting
bogus data.

Tmu_get_temp will get called as a part of sensor registration via
devm_thermal_zone_of_sensor_register(). To prevent it from retruning
bogus data we need to enable sensor monitoring before that. Looking at
the datasheet (i.MX8MQ RM) there doesn't seem to be any harm in
enabling them all, so, for the sake of simplicity, change the code to
do just that.

Convert driver to use regmap API, drop custom LE/BE IO helpers and
simplify bit manipulation using regmap_update_bits(). This also allows
us to convert some register initialization to use loops and adds
convenient debug access to TMU registers via debugfs.

We can simplify error cleanup code if instead of passing a "struct
platform_device *" to qoriq_tmu_calibration() and deriving a bunch of
pointers from it, we pass those pointers directly. This way we won't
be force to call platform_set_drvdata() as early in qoriq_tmu_probe()
and consequently would be able to drop the "err_iomap" error path.

Embed per-sensor data into struct qoriq_tmu_data so we can drop the
code allocating it. This also allows us to get rid of per-sensor back
reference to struct qoriq_tmu_data since now its address can be
caluclated using container_of().
