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.

esp8266: Implement software SPI class.
...
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins. Only supports MSB output at the moment.

esp8266: Expose pin object as a public structure for use as C pin API.
...
This is an initial attempt at making a simple C pin API for writing
things like I2C drivers in C.

esp8266: Make pyb.RTC a type, and pyb.RTC() constructs an RTC object.
...
This is the standard way of doing things, one should construct a
peripheral object (even if it's a singleton).
See issue #1330 .
