The eswifi controller is capable of acting as an Access Point.
Implement ap_enable/ap_disable methods.

Create eswifi_at_cmd and eswifi_at_cmd_rsp helpers, allowing to send an
at command and parse the at response. These methods return success if
the response contains the OK* string. The eswifi_at_cmd_rsp method
extracts response content/size (DATA) on success.
*Response format is:
\r\n[DATA]\r\nOK\r\n>
Where DATA can be arbitrary (ASCII or not).

The introduction of -fno-common caused a link error in eswifi driver due
to lack of missing extern on eswifi_bus_ops_spi. Adding the extern
resolves the link error.

This patch adds support for blocking tcp receive (with timeout).
This patch removes dedicated socket polling thread to use common
eswifi workqueue instead.

Current implementation unconditionnaly performs blocking connect
and send. Add support for non-blocking version using eswifi workqueue.

We were hard coding the SPI bus name to "SPI_3". Instead we should use
DT_INVENTEK_ESWIFI_ESWIFI0_BUS_NAME as its generated from the device
tree.

The driver was using the straight alias generated defines, however we
want to use DT_ prefixed defines so its clear that the values are coming
from DT.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

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!
