The spi drivers now consistently select HAS_DTS_SPI, so we no longer
need to select it at the board level.

Makes the designware spi driver consistent with other spi drivers by
selecting HAS_DTS_SPI in the driver. This required adding spi nodes and
dts fixups to several arc and x86 socs, as well as enabling those nodes
in associated boards.
Also refactors the driver to use the base address, interrupt number, and
interrupt priority from dts.

We get several warnings of the form:
Warning (unit_address_vs_reg): /cpus/arcv2-intc@0:
node has a unit name, but no reg property
Fix by removing the unit address from the nodes. Some cases we had a
reg property and a unit address for such interrupt controllers, in those
cases remove both the reg & unit address in the node name.

These symbols were removed by commit ed26b95 ("drivers/gpio:
Removing dts generated options in QMSI Kconfig"). The settings should
come from DTS now.
Commit 9611002f7a ("boards/x86: Use right GPIO names for CC2520")
fixed some of the references, but there are still others left. Guess
that the same fix is appropriate in those spots (hardcoded
"GPIO_0"/"GPIO_1" names).

SPI_DW_PORT_{0,1,2,3}_INTERRUPT_SINGLE_LINE in commit 423f0095c7

Remove the assignment and set SPI_DW_PORT_0_INTERRUPT_SINGLE_LINE to 'n'

The current method of setting the openocd runner arguments works for
direct invocation from the command line, but the values that are
written to the CMake cache are not properly separated and are
difficult to parse, due to the fact that in several cases, option
values contain spaces.
Adjust these runner arguments so that the options and their values are
separate list items. This makes it possible to parse them accurately
from the CMake cache.
No functional changes.

The original em7d, em9d and em11d are different configurations of
em_starterkit. They have the same peripherals, e.g. uart, spi, gpio
, ddr. The differences of them are in arc core configurations, interrupt
number assignment.
So em7d, em9d and em11d can be viewed in the same SoC family or SoC
series.
Referring other arch's implementation, this commit merges em7d, em9d
and em11d into the same SoC, named snps_emsk. This will eliminate
unnecessary duplication and make it easier for future maintainment.

1000 ticks per second is a little heavy for it.

* for the kernel thread, the privilege stack is also a
part of thread stack, the start of stack can be configured
as stack guard
* for the user thread, no stack guard, when the user stack is
overflow, it will fall into kernel memory area which requires
kernel privilege, privilege violation will be raised
* modify the linker template and add MPU_ADDR_ALIGN
* add user space corresponding codes in mpu
* the user sp aux reg will be part of thread context
* When user thread is interruptted for the 1st time, the context is
saved in user stack (U bit of IRQ_CTLR is set to 1). When nest
interrupt comes, the context is saved in thread's privilege stack
* the arc_mpu_regions.c is moved to board folder, as it's board
