The contents of machine_mem.h, machine_i2c.h and machine_spi.h have been
moved into extmod/modmachine.h.

The machine_i2c_type, machine_spi_type and machine_timer_type symbols are
already declared in extmod/modmachine.h and should not be declared anywhere
else.
Also move declarations of machine_pin_type and machine_rtc_type to the
common header in extmod.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. For all ports except the two listed
below there is no functional change.
The nrf port has UART.sendbreak() removed, but this method previously did
nothing.
The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

These include ADC, DAC, I2C, SoftI2C, SPI, SoftI2C, PWM, UART, pulse. This
is useful for devices like the Adafruit Trinket series which have almost no
accessible GPIO pins.

Applies to both SPI and I2C. The underflow caused high baudrate settings
resulting in the lowest possible baudrate. The overflow resulted in
erratic baudrates, not just the lowest possible.
Protect SerCom (UART, SPI, I2C) objects from getting freed by the GC when
they go out of scope without being deinitialized. Otherwise the ISR of a
Sercom may access an invalid data structure.
