With the phy-clock being specified in devicetree (and thus under user
control), there is no need to artificially enlarge the DPHY clock to
insure it is fast enough. Instead, we can calculate the DPHY clock
directly, selecting the closest realizable value that is at least as
fast as the value requested by the user.

Currently MIPI devices are set to initialize before display drivers,
which is incoherent with how the mcux mipi-dsi device is declared in the
device tree.
This is detected with build time priority checking:
west build -p -b mimxrt595_evk_cm33 samples/drivers/display \
-DCONFIG_CHECK_INIT_PRIORITIES=y
ERROR: /soc/peripheral@50000000/mipi_dsi@31000 POST_KERNEL 40 <
/soc/peripheral@50000000/lcdif@210000 POST_KERNEL 85
Note that this also changes the priority of dsi_stm32, though that
should be ok since does not appear to have other dependencies in
devicetree.

Update MCUX ELCDIF driver to use new LCDIF bindings. This
update also adds support for configuring the root clock of
the ELCDIF module based on the pixel-clock property to the
RT11xx SOC clock init, as this SOC series has this IP block

Update DCNANO LCDIF IP to use shared lcd interface binding. This
requires changes to the RT5xx SOC and RT595 EVK, as this SOC
uses the LCDIF IP, and configures the clock for it based off
the new pixel-clock property.

Introduce phy-clock property, which is used by MIPI devices to determine
the target clock frequency for the MIPI PHY. This property can vary
depending on the attached display and target framerate.
Update the MIPI DSI MCUX driver to utilize this property to configure
the MIPI host, and update the RT500 clock initialization to configure
the MIPI root clock based on this property.
Remove dphy-clk-div property from the MIPI DSI 2L binding, as it
is redundant with this change.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

Introduce driver for MCUX MIPI DSI 2L. This IP block differs slightly from
the existing MCUX MIPI peripheral, and uses a different hardware
abstraction layer. For these reasons, a new driver was introduced rather
than extending the existing mcux_dsi implementation.

It looks like this platform is using soc.h to declare some display APIs,
imxrt_pre/post_init_display_interface(). This likely deserves a better
design, but for now let's fix compiler warnings.
