With the introduction of the new device-tree macros it is now possible
to use the settings for speed and flow-control from the bus node instead
of having the same properties on the esp node itself.

And implement DT_ANY_INST_ON_BUS() in terms of it.
This makes some error messages quite a bit shorter by avoiding
UTIL_LISTIFY(), which has a nasty temper and tends to explode if not
treated gently.

The label property of the fixed-partitions child binding was duplicated
with two different values. This is invalid yaml, but went unnoticed by
pyYAML. Removed first entry to preserve value produced by pyYAML
behavior of overwriting duplicates.

This is joint work with Kumar Gala (see signed-off-by).
Add helper macros which abstract the "true names" of each of the four
types of node identifier we intend to support (e.g. DT_ALIAS(),
DT_INST()).
These can be passed to a new DT_PROP() macro which can be used to read
the value of a devicetree property given a node identifier from one of
these four other macros, and the as-a-c-token name of the property.
Add other accessor macros and tests as well.
Add some convenience APIs for writing device drivers based on instance
numbers as well. Drivers can "#define DT_DRV_COMPAT driver_compatible"
at the top of the file, then utilize these DT_INST_* macros to access
various property defines.
For example, the uart_sifive driver can do:
#define DT_DRV_COMPAT sifive_uart0
Then use DT_INST macros like:
.port = DT_INST_REG_ADDR(0),
.sys_clk_freq = DT_INST_PROP(0, clock_frequency),
For convenience working with specific hardware, also add:
<devicetree/gpio.h>
<devicetree/adc.h>
<devicetree/spi.h>

The `xlnx,ttcps` binding, despite having the file name of
`xlnx,ttcps.yaml`, had the compatible property of `cdns,ttc`.
While it is true that the Xilinx ZynqMP platform embeds the Cadence
Triple Timer Counter (TTC) IP core, its TTC differs from the original
Cadence core in that it implements 32-bit counters, instead of the
16-bit counters defined in the original; hence, the Xilinx variant is
not compatible with the original Cadence version and should be treated
as a different device.
This commit changes the `xlnx,ttcps.yaml` compatible property to
`xlnx,ttcps` for the above reasons.

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:
