Wrap the generated code in a `const _: ()` block to avoid symbol conflict.
This removes the need of creating a new identifier.

Add a 'bound lifetime to the associated Data, changing type Data to type
Data<'bound>.
This allows the driver's bus device private data to capture the device /
driver bound lifetime; device resources can be stored directly by
reference rather than requiring Devres.
The probe() and unbind() callbacks thus gain a 'bound lifetime parameter
on the methods themselves; avoiding a global lifetime on the trait impl.
Existing drivers set type Data<'bound> = Self, preserving the current
behavior.

Device<Core> references in probe callbacks are scoped to the callback,
not the full binding duration. Add a lifetime parameter to Core and
CoreInternal to accurately represent this in the type system.

Add a type Data<'bound> associated type to all bus driver traits,
decoupling the driver's bus device private data type from the driver
struct itself.
In the context of adding a 'bound lifetime, making this an associated
type has the advantage that it allows us to avoid a driver trait global
lifetime and it avoids the need for ForLt for bus device private data;
both of which make the subsequent implementation by buses much simpler.
All existing drivers and doc examples set type Data = Self to preserve
the current behavior.

C-String literals were added in Rust 1.77. Replace instances of
`kernel::c_str!` with C-String literals where possible.
