Commit 43530b69d758328d3ffe6ab98fd640463e8e3667 ("regulator: Use
regmap_read/write(), regmap_update_bits functions directly") intended
to replace working inline helper functions with standard regmap
calls.  However, it also inverted the set/clear logic of the "CORE ADJ
Allowed" bit.  That patch was clearly never tested, since without that
bit cleared, the core VDCDC1 voltage output does not react to I2C
configuration changes.

This patch fixes the issue by clearing the bit as in the original,
correct implementation.  Note for stable back porting that, due to
subsequent driver churn, this patch will not apply on every kernel
version.

Add device tree based initialization support for tps65023 regulators.
Therefore add macros for regulator definition setting of_match and
regulators_node members. Add initialization of regulator_desc data
using these macros. Remove old regulator_desc initialization.

Add device tree binding document for tps65023 regulators.

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

The regmap_config struct may be const because it is not modified by
the driver and regmap_init() accepts pointer to const. Make struct
regulator_ops const as well.

Since commit b42261078a91 ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.

So remove the I2C_FUNC_SMBUS_BYTE_DATA functionality check in the driver code.
