This adds support for the Espressif ESP8266 and ESP32 devices to be used
as peripherals on a UART.
There are two main AT command versions that can be selected, 1.7 and
2.0. Since they behave a bit different it is important to select the
one that matches the used in the firmware on your device.
When downloading large amounts of data it is highly recommended to
enable CONFIG_ESP_PASSIVE_TCP and flow control on the UART so that
data is not lost due to UART speed or receive buffer size.
Currently unsupported:
- Changing UDP endpoint with a sendto()
- Bind to a specific local port
- Server socket operations, ie listen() and accept()
Official AT firmware for ESP8266 and ESP32 can be found at:

missing licensing information, which makes it harder for compliance
tools to determine the correct license.

es-WiFi compatible modules use IWIN AT command set.
This driver is split into several layers:
- bus layer: interface to transmit AT commands (SPI, USB, UART...)
- core layer: es-WiFi module management (state, scan...)
- offload layer: TCP/IP offload operations (connect, listen...)
This driver has been tested with stm32l4 disco iot board
(disco_l475_iot1) and the wifi sample:
$ select wifi
$ scan
$ connect "CISCO" 5 password
$ select net
$ tcp connect 192.168.1.21 4242
$ tcp send HelloWorld!

Place simplelink driver files into a subdirectory on par with
winc1500 subdirectory, to effect a better file organization.
No functional change in this patch.

Initiate a SimpleLink WiFi Driver, implemented to the WiFi management
offload APIs for scan, connect, disconnect.
Also registers the DHCP-obtained IPv4 address upon connect.
This was validated on a cc3220sf_launchxl using the wifi
shell module from the Zephyr shell_module sample.

There will be other drivers, and mixing up all these files together will
create a mess so better having a dedicated place for winc1500, at least.

Adding support for WINC1500 WiFi chip.
It introduces the wifi drivers sub-directory.
It provides a Full-MAC for 802.11 and an offloaded network stack as
well. The driver uses Atmel's winc1500 HAL.
