char: don't limit data sent to backends to 1k per buffer
chardevs have a 'can_read' function via which backends specify
the amount of data they can receive. When can_read returns > 0,
apps can start sending data. However, each chardev driver here
allows a max. of 1k bytes inspite of the backend being able to
receive more.
The best we can do here is to allocate s->max_size bytes from
the heap on each call (which is the number returned by the
backend from the can_read call).
This is an intermediate step to bump up the bytes written in
each call to 4k.
