The `arm-gic.h` file distributed by the Linux kernel is disjunctively

The Arm Generic Timer specification mandates that the
interrupt associated with each timer is low level triggered,
see:
Arm Cortex-A76 Core:
"Each timer provides an active-LOW interrupt output to the SoC."
Arm Cortex-A53 MPCore Processor:
"It generates timer events as active-LOW interrupt outputs and
event streams."

describe interrupt types as edge rising
IRQ_TYPE_EDGE_RISING = 0x01:
interrupts = <1 13 0xff01>,
<1 14 0xff01>,
<1 11 0xff01>,
<1 10 0xff01>;
, see include\dt-bindings\interrupt-controller\arm-gic.h:
which causes Linux to generate the warnings below:
arch_timer: WARNING: Invalid trigger for IRQ5, assuming level low
arch_timer: WARNING: Please fix your firmware
This patch adds GIC_CPU_MASK_RAW macro definition to
include\dt-bindings\interrupt-controller\arm-gic.h,
modifies interrupt type to IRQ_TYPE_LEVEL_LOW and
makes use of type definitions in arm-gic.h.

The drivers are also updated to reflect the changes.
Set RCC as non-secure.
