e0a418c1e3 drivers: wifi: esp: constify modem_cmd and setup_cmd structures
Constifying global data allows to save lots of RAM. Defining data inside
function as 'static const' allows on the other hand to save stack usage
and reduced code size (because data doesn't have to be copied on stack
in runtime).

This improvement allows to save 640 bytes of RAM and 64 bytes of ROM
when compiled on ARM.

2bab204ba3 drivers: wifi: esp: increase default RX net_pkt allocation timeout
So far there was 100ms timeout on allocation of RX net_pkt. This is too
little for cases when lots of data are incoming on pretty
fast (e.g. 1Mbps) UART interface and application layer does not consume
received network packets fast enough. Up to now in such cases all
incoming data was processed from UART and there was no data loss when
utilizing hardware flow control. However there was high chance that data
processed from UART could not be passed further to network stack,
because of the 100ms net_pkt allocation timeout. This happens for
example when low priority application does not have enough time to run.

Increase default RX net_pkt allocation timeout from 100ms to 5s, so
there is much more time to process network packets. Such timeout should
not harm, because only a dedicated RX thread will be suspended for that
time, resulting in suspending UART traffic if hardware flow control is
supported.

b3272f3fe8 drivers: wifi: esp: allocate in modem_cmd_handler with K_NO_WAIT
All net_bufs allocated to modem_cmd_handler's data->rx_buf are consumed
synchronously in esp.c in the same thread. This means that allocating
them with timeout makes no sense, because timeout will *always* be hit
when there are no more buffers in net_buf_pool.

Get rid of the unnecessary timeout, as it doesn't help and just slows
down processing of incoming data, increasing possibility of data
overrun.

318cbe649a drivers: modem: cmd_handler: rework reading from interface
So far a dedicated buffer was used for data read from modem
interface. New net_bufs were allocated and filled later, which means
that data was lost when no more net_bufs were available in the pool.

Prevent data loss by allocating net_buf before attempting any read on
modem interface. Process incoming data in a loop as long as reading from
interface results in new data. Also remove dedicated buffer
(data->read_buf) and directly fill net_buf content instead. As a side
effect there are less memory copy operations and RAM usage is reduced.

Pre-allocated net_buf is now always appended to data->rx_buf. When there
was no (more) data read from interface to such net_buf, then this empty
net_buf will be on the end of data->rx_buf fragment list. Update
skipcrlf() and findcrlf() implementations to explicitly check for each
net_buf length, instead of blindly assuming them to have at least single
byte.

Add power-gpios device-tree binding property to power on module before
communicating with it. This pin is called CHIP_PU in case of ESP32{,-S2}
and CHIP_EN in case of ESP8266. Dedicated reset pin is available only on
the latter, however Espressif recommends (in ESP8266 Hardware Design
Guidelines) to use CHIP_EN instead. Follow those recommendations and use
power-gpios to reset chip if that is provided over device-tree.

Configure power-gpios and reset-gpios as inactive by default, so that
chip becomes ready after executing esp_reset() function, either if one
or both are provided over device-tree.
