Add basic support for the Aesc Silicon GPIO controller.
This IP core has internal tri-states and therefore a read,
write and direction registers. Additionally, it has advanced
monitoring capabilities for interrupt generation; low or
high leve and rising or falling edge.
Interrupt support will be added later when ElemRV supports
interrupt in Zephyr.

Using the mpidr of the core to lock the hwspinlock meant it acted as
a spinlock in the cluster itself, which is exactly the opposite of what we
tried to achieve.
Additionally, this tied the driver to the arm architecture, even though the
HW was not.

The i.MX 91 Quick Start Board (MCIMX91-QSB board) is a platform designed
to display the most commonly used features of the i.MX 91 applications
processor. The MCIMX91-QSB board is an entry-level development board
with a small and low-cost package. The board can be used by developers
to get familiar with the processor before investing a large amount of
resources in more specific designs.

The ADC and COMP on the nrf54h20 both have all of their analog
inputs routed to pads in different power domains than themselves,
this means the device drivers for both of them need to request the
pads to be resumed when active to allow any reading of the pads.
To keep the drivers simple, we can rely on HW to keep the power
domain the COMP and ADC are in powered, which happens automatically
when the ADC or COMP is ENABLED. We can then place them on the
power domain of their pads in the devicetree. This ensures the pads
are powered and not retained while the devices are RESUMED.

During testing with teensy 4.0 it was discoverd that toggling
at high frequencies led to missed steps. As per the datasheets
of step-dir drivers an active edge needs to be maintained for
a certain timerperiod, for a step to be executed.
Instead of toggling pin twice instantaneously, the current fix
halves the step period and the step-pin is toggled on the timeout
of the respective timing source.
rework stepper stepper stop
set step pin to low if the driver does not support dual edge
and increment/decrement the actual position by one
