Gerard Marull-Paretas b2a1eeb6ac soc: arc: define ICI in DT
ICI (Inter-Core Interrupt Unit) interrupts and priorities were hardcoded
in C files. This patch moves this information to Devicetree and updates
code to make use of it.

Gerard Marull-Paretas 754c022fa2 soc: arc: snps_arc_iot: define sysconf in DT
sysconf base address was hardcoded in <soc.h>. Create a new compatible
and define it in Devicetree, where hardware needs to be described.

Gerard Marull-Paretas 5f40a9f40f soc: arc: synopsys: move secure timer0 definition to DT
Use Devicetree to describe secure timer0 instead of hardcoding values in
<soc.h>.

DT files have been structured to match the following requirements: In
case of sectimer0 - it's should be only enabled for:

- emsdp_em7d_esp.dts
- em_starterkit_em7d.dts
- nsim_sem_mpu_stack_guard.dts
- nsim_sem.dts

Gerard Marull-Paretas 44250fe3d3 soc: arch: synopsys: move timer0/1 IRQ information to DT
timer0/1 IRQ information was hardcoded in soc.h, however, Devicetree is
nowadays a better place to describe hardware. Note that I have followed
existing upstream Linux code to do these changes.

Kumar Gala 762eadc15d drivers: gpio: dw: rework init to use DT_INST_FOREACH_STATUS_OKAY
Use DT_INST_FOREACH_STATUS_OKAY to reduce duplicated code for each
instance.

We make interrupts optional since they aren't always available.

Gerard Marull-Paretas 4c8a8149de dts: add reg-shift property to all ns16550 devices
The ns16550 flags reg-shift property as optional. In case it is not
supplied, the ns16550 driver relies on a value defined in <soc.h>, or,
by default it takes 4 (shift by 2).

This patch adds the property to all ns16550 nodes, with the following
values:

- 2 if SoC did not have any custom value defined by
  UART_REG_ADDR_INTERVAL (corresponds to 1 << 2 = 4)
- If SoC defined DEFAULT_REG_INTERVAL (snps_arc_iot/it8xxx2), use such
  value (4=2, 2=1, 1=0).

These changes will allow simplifying the ns16550 driver.

Evgeniy Paltsev f81b3e03ac ARC: boards: HSDK: ged rid of pinmux usage
Pinmux is deprecated (see #39740) so let's get rid of
it's usage for HSDK board.

As we call pinmux only once at init phase we simply do
register setup in platform code instead of pinmux.
