[PATCH 2/5] hwmon: (pmbus/adm1275) Use pmbus_read_smbus_i2c_block_data for block commands

[Guenter Roeck <linux@roeck-us.net>]

The driver uses i2c_smbus_read_block_data() for PMBus block commands.
Use pmbus_read_smbus_i2c_block_data() instead to enable the driver to work
with I2C controllers which do not support i2c_smbus_read_block_data().

Drop the functionality check to get an explicit error message if the
required SMBus commands are not supported.
