Daniel Almeida 2e0fd4583d rust: regulator: add devm_enable and devm_enable_optional ...

A lot of drivers only care about enabling the regulator for as long as
the underlying Device is bound. This can be easily observed due to the
extensive use of `devm_regulator_get_enable` and
`devm_regulator_get_enable_optional` throughout the kernel.

Therefore, make this helper available in Rust. Also add an example
noting how it should be the default API unless the driver needs more
fine-grained control over the regulator.
