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.
