The WCH External Trigger and Interrupt controller (EXTI) supports
between 8 and 22 lines where each line can trigger an interrupt on
rising edge, falling edge, or both edges. Lines are assigned to a
group, and each group has a separate interrupt. On the CH32V003/6,
there is one group of 8 lines, while on the CH32V208 there are
multiple groups with between one and six lines per group.
In the same way as the STM32 and GD32, define an EXTI driver that
configures the peripheral and an internal interface that can configure
individual lines.

Replace the use of `DT_NODELABEL(exti)` which depends on the node label
with the defined EXTI_NODE macro using the instance with the
`st_stm32_exti` compatible.
Since both macros point to the same node, this change doesn't affect
the code logic, but makes it independent of the node label, in
preparation for the addition of the STM32MP2 exti nodes.

So far, it has been assumed that only level 2 interrupts can be shared
via the `CONFIG_SHARED_INTERRUPTS` option, but this is not true. In the
case of i.MX95, for instance, level 1 interrupt 143 is shared among EDMA
channels 30 and 31.
Due to the previous assumption, the irqsteer driver currently performs
reference counting for all level 2 interrupts aggregated by each
dispatcher and, of course, for the level 1 interrupts the dispatchers are
attached to. For instance, assuming a machine with 100 level 1 interrupts
and 1 irqsteer dispatcher attached to line 50 this would mean reference
counting is performed solely for line 50 (and the level 2 interrupts MUX'd
into this line).
Going back to i.MX95, since there's no dispatcher attached to IRQ line 143
that means there's no reference counting for it. In turn, this means that
the IRQ line can be disabled accidentally on a channel release() operation
while the other channel is active.
To protect against such cases, refactor the level1 interrupt reference
counting. Now, reference counting is performed for _all_ level 1
interrupts.
Additionally, simplify the locking logic. Ideally, there would be a lock
for each dispatcher protecting the level 2 interrupts and 1 global lock
protecting the level 1 interrupts. Instead of this approach (which is a
bit more complex), simply use a global lock for all interrupts. If finer
granularity is required then it can be added later on.

For GIC multiple views feature support, all GIC Re-distributor's
GICR_TYPER.last will be set. Because configuration view-0 can
assign non-contiguous CPUs to views other than 0, in this case
the GIC Redistributors' registers won't seem contiguous.
So the GIC driver should cope with multiple sets of redistributors
like multi-chip scenarios. In this patch we add multiple GIC
redistributor regions support in GIC redistributor iteration.
