A throw once master enable switch to protect against any
further overlay applications if the administrator desires so.

A kernel command line option is provided as well.

We are going to need the overlays to appear on sysfs with runtime
global properties (like master enable) so turn them into kobjects.

They have to be in sysfs so that people can have information about the
overlays applied in the system, i.e. where their targets are and whether
removal is possible. In a future more attributes can be added
in a backwards compatible manner.

Add a runtime interface to using configfs for generic device tree overlay
usage. With it its possible to use device tree overlays without having
to use a per-platform overlay manager.

Please see Documentation/devicetree/configfs-overlays.txt for more info.

Changes since v6:
- Default groups properties API changed.

Changes since v5:
- New style configfs.

Changes since v4:
- Loading fix for multiple overlays as found out by
  Geert Uytterhoeven <geert@linux-m68k.org>

Changes since v3:
- Fixed compilation on SPARC & Xtensa

Changes since v2:
- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
- Created a documentation entry
- Slight rewording in Kconfig

Changes since v1:
- of_resolve() -> of_resolve_phandles().

Confine the memory map changes into a separate rtos-memory-map.dts
which describes the common memory map for all RTOS remoteprocs.

vision-apps.dtbo uses this and also disables capture and display
related peripherals from Linux so that it can be used by RTOS.

edgeai-apps.dtbo expects these devices to be owned by linux, so
it uses the rtos-memory-map customization only.

Signed-off-by: LCPD Auto Merger <lcpd_integration@list.ti.com>

The parent's input irq number is wrongly subtracted with 32 instead of
using the exact numbers in:

https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721s2/interrupt_cfg.html



The GPIO interrupts are not working because of that. The toggling works
fine but interrupts are not firing. Fix the parent's input irq that
specifies the base for parent irq.

Tested for MAIN_GPIO0_6 interrupt on the j721s2 EVM.

PCIe lane mask should be based on the maximum number of lanes and not the
currently selected lane count, since we have no idea what the bootloader may
have initialized to this register.

In the previous version of devicetree, reserved area for wakeup
R5F was stating from 0x9db00000, so to provide compatibility
with older version of devicetree being used with new wakeup R5F
firmware, the wakeup R5F reserved area is reduced by 1Mb and that
1Mb is moved to MCU M4F reserved area.

While pruning is useful for making small and fast-building kernels for
our SDK releases, these are not so useful for general purpose or distro
kernels where these options might still be needed.

Move all the pruning from audio_display.cfg into multi_v7_prune.cfg.
