This adds automatic GPIO latching before going to extended sleep and
restoring state after wakeup.
Mode and state for each pin is stored, then ports are latched to retain
state when PD_COM is disabled during sleep. On wakeup mode and state for
each pin is restored and ports are unlatched to make it work again.

Extended sleep is low power mode where ARM core is powered off and can

The AM64x and AM62x are both SOCs from the TI K3 family
and share common architecture designs. The M4F subsystem
is actuall identical on both SOCs.
Therefore, just add all missing CONFIGs, files, etc. to
support the AM6442x SOC.
Since MMR and RAT initialization are identical too, both
functions can be re-used. However, since they might
differ in the future, the am64x has it's own init
function.

Prevent the CPU from entering deep doze mode when JTAG debug is enabled.
Additionally, The CPU address from 0x80000800 to 0x800008FF should be

A workaround to avoid icache corruption was added in commit be881d4cf2
("arch: xtensa: add isync to interrupt vector").
This patch implements a different workaround by adding custom logic to
idle entry on affected Intel ADSP platforms. To safely enter "waiti"
when clock gating is enabled, we need to ensure icache is both unlocked
and invalidated upon entry.

This commit introduces a common API for managing nRF53 SoC network CPU
Force-OFF state.
From the application CPU point of view, the network CPU is a shared
resource used by multiple users. The current solution where every user
controls the network core state directly leads to dependencies between
users and does not scale well.
To address this problem there should be a single entity responsible for
controlling the network CPU Force-OFF signal. This commit introduces
such module.

Nordic SoCs use this hook to execute `SystemInit` as early as possible
after ARM core reset. Previously, `z_arm_platform_init` was defined as
assembly code, which would simply jump to the other function.
However, this extra code can be avoided by using `SystemInit` directly
in place of the `z_arm_platform_init` symbol (whenever it's undefined).
This is now done with a linker script containing a `PROVIDE` directive.
This saves 4 bytes of ROM (0-16 depending on alignment) and also makes
it possible to override `z_arm_platform_init` out of tree, if needed.

We need to use correct SOC name when naming the Kconfig.defconfig*
files.
So we need the following changes:
- mimx8mp -> mimx8ml8
- mimx8mm -> imx8mm6
- mimx8mn -> mimx8mn6
- mimx8mq -> mimx8mq6
Then we also need to take care of qualifiers name. Standard notation
uses "_" instead of "."
e.g : Kconfig.defconfig.mimx8mp.a53 -> Kconfig.defconfig.mimx8ml8_a53

Prevent the system from entering runtime idle state during IPC
transactions until the HOST acknowledgment is received.
This patch modifies the IPC mechanism to:
- Lock the runtime idle state immediately after sending an IPC message
to the HOST, preventing the system from entering a low-power state.
- Unlock the runtime idle state once the IPC transaction is acknowledged
by the HOST, allowing the system to enter low-power states if
conditions permit.
The changes ensure that the DSP does not enter a power state that could
interrupt the IPC communication process, maintaining the integrity of
the IPC state machine.
