For aesthetics, add some whitespace to the subdevice init.
This driver does not support async commands so remove the dev->read_subdev
initialization.
Remove the commented out SDF_COMMON from the subdevice subev_flags.
Add the subdevice range_table initialization.
For aesthetics, rename the (*insn_{read,write}) functions so they have
namespace associated with the driver.
Remove the unnecessary comments about the (*insn_{read,write}) functions.
