In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Clean up of pin signals definitions previously used
by the pinmux driver, now deprecated by the use of
the pinctrl API.
Refactor device tree macros usage to make usage of
SPI instances more general.

ESP32C3 requires master init call to enable its clock
gate. Without this, SPI interface may not initialize
properly.

In case when we have multiple devices connected to the
one SPI interface the initial state of CS gpios after
MCU reset is floating and it might be low that prevents us from
communicating between particular devices. Fix that by
initializing all provided cs gpios and setting them as inactive.

A couple of SPI drivers use CONFIG_KERNEL_INIT_PRIORITY_DEVICE
as init priority for driver initialization. Let's change
it to the dedicated CONFIG_SPI_INIT_PRIORITY to make it
compatible with other ones.

Replaces the prefixes of gpio_matrix_in and gpio_matrix_out
to unify those function calls on all supported socs.

Max SPI chunk len was missing from the
implementation, causing SPI to hang up in some
conditions.

hal_espressif repository was updated from esp-idf v4.2
to esp-idf v4.3 to allow latest Espressif chips integration.
As a consequence, it added a few changes in drivers
and peripherals. To maintain bisectability, changes in this
PR cannot be split. Here are some details:
wifi: update linker script by adding libphy and new attributes.
spi: update some APIs and fixed missing wait_idle check
west.yml: esp32: update hal to new version
