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

a6aa35af09 esp8266: Move pyb.info() function to esp module and remove pyb module.
All functionality of the pyb module is available in other modules, like
time, machine and os.  The only outstanding function, info(), is
(temporarily) moved to the esp module and the pyb module is removed.

a2d5d84ecc esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer.
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.

If the full pin object is needed then it can be easily looked up in the
pin table.

a9a732af1f esp8266: Remove pin_id field from C pin object.
This field is the same as phys_port and not needed.

1a65ff1b72 esp8266: Protect modpyb.h header file from multiple inclusions.
Also include py/obj.h so the header is self contained.

1a0a323ca8 esp8266: Add initial implementation of machine.UART.
Currently UART(0) and UART(1) are exposed and only uart.write works.

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.

82b95f625e 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.

7059c8c23c 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.

de8b585ab7 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.
