Kernel: Changed serial debug functions and variables for readability

Browse source 
Change the name of set_serial_debug(bool on_or_off) to
set_serial_debug_enabled(bool desired_state). This is to make the names
more expressive and less unclear as to what the function does, as it
only sets the enabled state.
Likewise, change the name of get_serial_debug() to
is_serial_debug_enabled() in order to make clear from the name that
this is simply the state of s_serial_debug_enabled.
Change the name of serial_debug to s_serial_debug_enabled since this is
a static bool describing this state.
Finally, change the signature of set_serial_debug_enabled to return a
bool, as this is more logical and understandable.
