  chips/atmega: Use BUILTIN defines to select tone code

Instead of requiring a separate SNEK_TONE define, use the existing
SNEK_BUILTIN_tone and SNEK_BUILTIN_tonefor defines to select whether
the tone code is included in the 328p io driver.

This lets the host perform automatic baud rate detection even if

  chips/atmega: Fix digital reads from "analog" pins

When a pull-up value is applied to an analog pin, snek is supposed to
go into digital mode, however, the function responsible for returning
the correct pin register wasn't set to return PINC for the analog pins.

  chips/qemu: Use semihost_elapsed for time values

QEMU returns processor time for sys_semihost_clock, so switch to
sys_semihost_elapsed(), which provides wall time instead.

  snekde: Support 57600 and 115200 baud

8MHz atmega devices cannot use 115200 baud because the clock
resolution isn't fine enough to get a close match in bit rate. So,
those devices will run at 57600 baud instead.

Support this by using the new ^T handling in the 328p chip code to
auto-detect the device baud rate when initially opening the device and
also adding a baud rate selection key (F8) which switches between
115200 and 57600 baud.

Display this in the status bar along with the device name.

  Add port to standard LilyPad

This is an ATMega 328P running at 8MHz because of the 3.3V power
supply.  This port includes the basic I/O code along with the 'tone'
builtins to support the LilyPad beeper when connected to pin 5. This
required leaving out dictionary and slice support to save flash.
