Add a display driver and the corresponding devicetree binding for a LED
matrix with rows and columns driven by nRF SoCs GPIOs. Such matrix can
be found, for example, in the BBC micro:bit boards.

don't support that the current thread change when writing a message with
printk (which uses poll_out). So, we remove the call to k_yield which is
useful only for optimizing cpu usage by forcing a thread change if the
usart send stack is full.

Call `gpio_stm32_clock_request` unconditionally with "true" if no
runtime PM is enabled, "false" otherwise. In case the GPIO was enabled
(e.g. by a bootloader), the device will be left in proper state when
runtime PM is enabled.
Also added pm_device_runtime_init_suspended to indicate that device is
in a suspended state (will prevent pm_device_runtime_enable to suspend
the device again).

The function is only used by the driver itself. This likely comes from
pre-runtime PM API usage.

The suspend operation for this device is a clock gating operation (i.e.

The PM runtime API (get/put) provides an inline implementation when not
built-in. Such implementation always returns 1, so it is safe to not
guard PM runtime calls and check for < 0.

The original parameter (k1) setting may let the I2C frequency be a
little bit higher than 100k Hz, which causes the timing Tsu:sta (set-up
time for a repeated START) to violate the spec. This change fixes the k1
parameter and also changes the HLDT to the suggested value in the
datasheet.

PRE_KERNEL_1 is to be used for devices that have no dependencies
and do not use kernel features, such as those that rely solely on
hardware present in the processor/SOC. This commit updates these
gpios to initialize during the PRE_KERNEL_1 rather than the
POST_KERNEL. Some SoC drivers are moved to PRE_KERNEL_2 due
to dependencies.
A lot of 'other' drivers can depend on GPIOs though phandles
(such as reset lines, data or command gpios, etc...). Most of these
drivers that would need this would come up on the POST_KERNEL,
and it's likely the driver may not be up yet as it should be defined.

USDHC driver did not pass disk test (failed during multiple writes). Add

To avoid the warning, make the struct non-packed, since it is not
necessary in this case given that a union already guarantees that the
