The shared IRQ code has been broken for several releases and no one
seems to have noticed. The platforms that this was used on are not
supported in Zephyr anymore so remove the code.

The device PM subsystem already holds the device state, so there is no
need to keep duplicates inside the device. The pm_device_state_get has
been refactored to just return the device state. Note that this is still
not safe, but the same applied to the previous implementation. This
problem will be addressed later.

Move all PM_DEVICE_STATE_* definitions to an enum. The
PM_DEVICE_STATE_SET and PM_DEVICE_STATE_GET definitions have been kept
out of the enum since they do not represent any state. However, their
name has not been changed since they will be removed soon.
All drivers and tests have been adjusted accordingly.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

PCI enumeration modifies pci_dev and base_addr at driver
initialization therefore these objects move from config_info to
driver_data in preparation for config_info becoming const.
We drop code that attempts to update irq_num based on PCI enumeration
because the interrupt found by PCI enumeration must always be the same
as the statically configured IRQ number.

The file gpio_dw_registers.h already had the 4-port GPIO
registers defined, yet the gpio_dw.c implementation didn't
support it properly. There are 4 ports here, not 2, and only
PORTA can support interrupts and debounce.
On the em_starterkit board, for example, PORTA
has 3 bits for buttons: A, L and R. The other 3 ports should not
be used with interrupts & debounce.
I've re-worked this file to derive the port number from the
base address given. The lower 6 bits are divided by 12 to
derive the port number. From this, the registers EXT_PORTA,
EXT_PORTB, EXT_PORTC or EXT_PORTD can be read.
Also, for those ports that don't support interrupts,
set irq_num to 0, and that code will be avoided. I've verified
that I can access GPIO now correctly on the EM Starterkit. The
em_starterkit board support will be submitted soon but I'm
staging in this change first.

Many sub-systems might require to set a callback on different pins.
Thus enabling it via changing the API.
It is also possible to retrieve private-data in the callback handler
using CONTAINER_OF() macro (include/misc/util.h).
Former API is still available, and is emulated through the new one.
Using both should not be a problem as it's using new API calls.
However, it's now better to start using the new API.
