[PATCH 0/5] hwmon: (pmbus/core) Introduce and use pmbus_read_smbus_i2c_block_data()

PMBus drivers need support for reading SMBus block data. Unfortunately,
not all i2C controllers support this command.

Implement pmbus_read_smbus_i2c_block_data() which first tries to use
i2c_smbus_read_block_data(). If not supported, try to emulate it by calling
i2c_smbus_read_i2c_block_data(). Export the new function for use in PMBus
drivers, and use it in affected drivers.
