7ddd1a58f6 esp8266/modmachine: Don't expose internal SoftSPI and HSPI classes. 
There functionality is available via standard SPI class.

1708fe3cc7 esp8266/modmachine: Add WDT_RESET and SOFT_RESET constants. 
Both tested to work. (WDT_RESET can be seen by issuing machine.disable_irq()
and waiting for WDT reset, SOFT_RESET - by machine.reset()).

8e7dfea803 esp8266/modpybhspi: Add a HSPI module for hardware SPI support 
This module uses ESP8266's SPI hardware, which allows much higher
speeds. It uses a library from

ee12581a35 esp8266: Let RTC work correctly after deepsleep. 
By design, at wake up from deepsleep, the RTC timer will be reset, but
the data stored in RTC memory will not [1]. Therefore, we have to adjust
delta in RTC memory before going into deepsleep to get almost correct
time after waking up.

So ets_loop_iter is now only disabled when using machine.disable_irq.

32d7cf6e44 esp8266: Implement basic deep-sleep capabilities. 
Use the machine.deepsleep() function to enter the sleep mode.  Use the
RTC to configure the alarm to wake the device.

Basic use is the following:

    import machine

    # configure RTC's ALARM0 to wake device from deep sleep
    rtc = machine.RTC()
    rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP)

    # do other things
    # ...

    # set ALARM0's alarm to wake after 10 seconds
    rtc.alarm(rtc.ALARM0, 10000)

    # enter deep-sleep state (system is reset upon waking)
    machine.deepsleep()

To detect if the system woke from a deep sleep use:

    if machine.reset_cause() == machine.DEEPSLEEP_RESET:
        print('woke from deep sleep')

632d8efa05 esp8266: Add PWM support. 
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.
