# Creates a Fuchsia driver assuming the driver's files start with the same
# naming scheme: "simple-${target_name}" where `target_name` is the name of the
# driver.
#
# This template assumes that the following files exist for the driver:
# * simple-${target_name}.bind - the driver's bind rules
# * ${target_name}_bind_tests.json - the driver's bind tests
# * simple-${target_name}.cc - the driver's C++ source code
# * simple.${target_name}-info.json - the driver's info
#
# Parameters
#
#   is_fallback (optional)
#     Whether or not the driver is a fallback driver
