ec: Use DEVICE_NOOP macro formalism over static stub func
The in source comment: /* This function avoids an error on serial console. */ refers to the resource allocator needing to find a non-NULL function pointer else complaints of "... missing read_resources" will be spewed. Unfortunately/fortunately (depending on the time of day) compiler optimisers have gotten a bit better at optimising away no-op functions leading to the very message these stubs attempted to avoid. By using the DEVICE_NOOP formalism that is static inlined 'suggests' (not enforces) to the compiler to keep these symbols around.
