Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

The imxrt1050 is configured to use SYSTICK for the kernel timer, but
SYSTICK cannot wake up the soc from low-power modes. Disable low-power
modes on this soc until we have support for an alternative timer.
This fixes k_sleep on the EVKB version of the mimxrt1050_evk board. An
earlier version of the board (EVK, not EVKB), had A0 silicon which
by default did not enter low-power mode on a wfi.

Set Zero Latency IRQ to priority level zero and SVCs to priority level
one when Zero Latency IRQ is enabled.
This makes Zero Zatency truly zero latency when the kernel has been
configured with userspace enabled, or when IRQ offloading is used.
Exceptions can still delay Zero Latency IRQ, but this is considered
ok since exceptions indicate a serious error, and the system needs to
recover.

The i.MX 6SoloX SoC is a hybrid multi-core processor composed by one
Cortex A9 core and one Cortex M4 core.
Zephyr was ported to run on the M4 core. In a later release, it will
also communicate with the A9 core (running Linux) via RPMsg.
The low level drivers come from NXP FreeRTOS BSP and are located at
ext/hal/nxp/imx. More details can be found at ext/hal/nxp/imx/README
The A9 core is responsible to load the M4 binary application into the
RAM, put the M4 in reset, set the M4 Program Counter and Stack Pointer,
and get the M4 out of reset.
The A9 can perform these steps at bootloader level after the Linux
system has booted.

Instead of finding the address of the spurious irq function in the
intList section we now rely on the linker to find the address in the
_irq_spurious symbol.
This is a migration from using code generation to using the C language
which we in the general case we should aways strive towards.
In this specific case it makes the generated code 'irq_tables.c'
easier to read as we replace magic numbers with the &_irq_spurious
token.
Also, the path through the build system that _irq_spurious makes is
much shorter, so it is much easier for a user to understand how it is
used.

The various STM32 reference manuals sometimes define the USB endpoints
as IN or OUT only and sometimes as bidirectional, even in the same
manual. This is likely because the OTG implementation has one set of
registers for the IN endpoints and one other set for OUT endpoints.
However at the end a given endpoint address can both transmit and
receive data.
This causes some confusion how to declare the endpoints in the device
tree, and depending on the SoC, they are either the same number of IN
and OUT endpoints declared, or they are declared as bidirectional. At
the end it doesn't really matter given how the driver uses those values:
#define NUM_IN_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_IN_ENDPOINTS)
#define NUM_OUT_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_OUT_ENDPOINTS)
#define NUM_BIDIR_EP NUM_OUT_EP
This patch therefore cleanup the driver, the DTS, and the DTS fixups to
only define the number of bidirectional endpoints.
In addition to the cleanup, that fixes a regression introduced by commit
52eacf16a2 ("driver: usb: add check for endpoint capabilities"), which
introduced a wrong check for SoC only defining the number of
bidirectional endpoints.
