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

Newer DTC now warns about mismatch between the reg and unit-address.
Most of these cases are due to case not matching, so fix thoses so
everything is lowercase.

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.

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.

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.
