Fix the following device tree warnings:
unit-address and first reg (0x20000) don't match for iccm@0
unit-address and first reg (0x80010000) don't match for dccm@80000000
Since the em_starterkit_em7d_normal has a different base address for
iccm & dccm, and most of the em_starterkit variants have different sizes
for iccm & dccm. Just define the nodes in the specific
em_starterkit*.dts file and remove them from emsk.dtsi. This removes
the issue reported in the warning.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with
git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'

As em7d is configured with HARVARD, CCM will be used not DDR,
SRAM should point to DCCM.
This bug will cause the wrong caculation of heap area,

There are different interrupt numbers for R22 v R23. Before this was
being handled via using Kconfig symbol CONFIG_BOARD_EM_STARTERKIT_R23 in
emsk_dt.h. Since we want to remove use of Kconfig in dts we handle this
via different dtsi files and having the proper one included by the
proper board revision dts file.

Towards removing Kconfig from DTS we need to move setting of the sizes
of ICCM/DCCM into the SoC specific DTS files and out of emsk_dt.h

Convert over arc based boards to use device tree instead of board.h to
describe buttons & LEDs. There are a few boards that the button gpio
flags need validation.

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.

Underscore ('_') isn't a valid char for alias names based on the device
tree spec. Newer dtc compilers flag this as a warning so lets clean it
up. Replaced '_' with '-' to keep things simple.

Add initial device tree support for the em{7,9,11}d SoC and associated
em_starterkit boards. The device tree at this point specifies cpu core,
memory, interrupt controller, uart's and i2c controllers.
