This patch removes the default value from some platform/SoC specific
options which are declared in drivers/watchdog/Kconfig because 1) most
of the time they are not valid values and 2) the correct values are
already set in the SoC Kconfig (e.g. arch/x86/soc/quark_d2000/Kconfig).
For Quark D2000, the IRQ priority options (WDT_DW_IRQ_PRI and WDT_QMSI_
IRQ_PRI) values are set to '0' since the priority information is ignored
by the interrupt registering system (the interrupt vectors are fixed in
this SoC).

This patch fixes the GPIO QMSI shim driver so we are able to use it in
Quark D2000 based platforms. To enable this driver we have to add a few
#if guards because some macros and functions (e.g. QM_AON_GPIO_0 and
qm_aon_gpio_isr_0) are not defined in QMSI headers from Quark D2000
(this SoC doesn't support the Always-On GPIO controller).
This patch also adds the QMSI driver default options to arch/x86/soc/
quark_d2000/Kconfig.

This patch fixes the QMSI I2C shim driver so we are able to use it in

driver is an #if guard in i2c_qmsi_init() because the macro QM_I2C_1

Since this drivers is now properly tested with Quark D2000, this patch
sets the QMSI driver default options in arch/x86/soc/quark_d2000/Kconfig.
It also adds the wiring information required to test the i2c_lsm9ds0

Having priority levels 0 and 1 reserved on x86 due to implementation
details on how the CPU uses the vector table is confusing to users,
and makes it unnecessarily difficult to share drivers between arches.
Now on x86, priority levels 0 and 1 are available. Semantically, all
priority levels have had 2 subtracted from them.
It is no longer necessary to specify a priority level when the
vector itself is specified. If an IDT entry has a specific vector
associated with it, any priority argument is simply ignored.
In gen_idt, some simplifications have been made:
- The printed representation of a generated entry now fits on one line
- Some checks being done in validate_priority() were redundant, as
generate_interrupt_vector_bitmap() also ensures that there are
sufficient free vectors within a priority level.

The argument to _common_dynamic_exc_handler() in the C domain
was still being set up the Sys V way. Arguments are popped off the
stack in reverse order, so _ExcEnt pushes *pEsf for arg 2, and then
the stub pushes the stub_num for Arg 1.
For IAMCU case, *pEsf is placed in EAX which is where argument 1
lives; static exception handlers take just one argument. However
since we're calling _common_dynamic_exc_handler we also need to
supply the stub_id, which we put in EDX (where arg 2 goes).
Rather than swapping things around at runtime the prototype for
_common_dynamic_exc_handler() is adjusted to fit the calling
convention in use.

Due to an issue with the interrupt-based transfer API from QMSI driver,
the 'transfer' callback from the shim driver (i2c_qmsi_transfer) is
implemented with polling APIs. This is not ideal because we are not able
to sleep the current thread (so another task can be scheduled in) while
the i2c operation is carried out.
The interrupt issue with the QMSI driver has been solved then this patch
fixes the shim driver so it uses the interrupt-based API and adds extra
code to handle the thread synchronization.
Finally, this patch also moves all 'struct device' related definitions
from the bottom to the top of the i2c_qmsi.c file so the DEVICE_GET
macro can be used in transfer_complete() and removes the init.h include
since it is not needed anymore.

Static interrupts rely on a trick where the _sw_isr_table array
is declared with each element in a different .gnu.linkonce
section, initially pointing to the spurious IRQ handler.
When drivers or apps declare their own interrupts, they override
the element with their own containing the real ISR and parameter.
However, this only works if the initial declaration of the
_sw_isr_table array with the spurious handlers is linked last.
App-specific code was being linked later than the core code,
causing static interrupts declared in apps not to be installed
correctly.
If the _sw_isr_table is moved from SOC-specific code to core arch
code, interrupts configured under soc/ should still also work.
