Set pinmux driver to use RTCIO interface for to handle
dedicated IOs pull-up/down configuration.
Without this, some GPIOS won't have pull-up enabled
properly.
Also, current implementation automatically disables
output pin when input pin is set. It also performs the

Fixes#40730.
A dead lock could happen if 2 threads with differents priorities use
poll_out. In fact, the lock data->tx_lock could be lock by a thread with
lower priority and then a thread with higher priority can't take the
lock. There was a race condition here:
/* Wait for TXE flag to be raised */
while (1) {
if (atomic_cas(&data->tx_lock, 0, 1)) {
/* !!!!!!!! RACE CONDITION !!!!!!!!!!!!!!
if (LL_USART_IsActiveFlag_TXE(UartInstance)) {
break;
}
atomic_set(&data->tx_lock, 0);
}
}
To fix race condition, the interrupts are locked in poll_out.

This commit adds a generic i2c regulator driver, and enables the NXP

Catch up on the CAN driver API argument naming changes:
- Unify naming of callback function pointers as "callback".
- Unify naming of user-specified callback function arguments as
"user_data".
- Instances and pointers to struct zcan_frame are named "frame",
not "msg", to avoid confusion with the CAN message queue support.

This commit adds Xen consoleio serial driver. It is needed to receive
kernel messages from Zephyr in case it runs as Xen privileged domain
(Dom0). There is no console ring buffer for such domain, so regular
uart_hvc_xen driver can not be used (privileged domain input/output
are possible only through consoleio interface).

This commit adds support of Xen Enlighten page and initial support for
Xen event channels. It is needed for future Xen PV drivers
implementation.
Now enlighten page is mapped to the prepared memory area on
PRE_KERNEL_1 stage. In case of success event channel logic gets
inited and can be used ASAP after Zephyr start. Current implementation
allows to use only pre-defined event channels (PV console/XenBus) and
works only in single CPU mode (without VCPUOP_register_vcpu_info).
Event channel allocation will be implemented in future versions.

This adds an spi master mode driver via bitbanged gpio. Only syncronous
transfers are implemented. Clock signal timing is accomplished via busy
waits, the gpios are manipulated via the standard gpio interface; these
two factors limit the frequency at which it can operate - but here
a simple and generic implementation was chosen over performance.
The driver supports the various clock polarity and phase
configurations, and can also work with word sizes which are non
multiples of 8bits, currently up to 16 bits.
A sample program is also added demonstrating basic use of the driver
with 9bit data words.

A Cortex-M specific function (sys_clock_isr()) was defined as a weak
function, so in practice it was always available when system clock was
enabled, even if no Cortex-M systick was available. This patch
introduces an auxiliary Kconfig option that, when selected, the ISR
function gets installed. External SysTick drivers can also make use of
this function, thus achieving the same functionality offered today but
in a cleaner way.
