Resolve the driver for this frame.

Mirrors Channel::resolveDynamicDriver() (channel.cpp.hpp), including the FASTLED_DISABLE_DYNAMIC_DRIVER gate – this controller never pre-binds a driver, so that gate simply drops every frame here, matching Channel::showPixels()'s non-pre-bound else branch under the same flag.
