Kumar Gala a5ae0daa35 dts: arc: Remove device_type = "memory" from {d,i}ccm nodes
The "{d,i}ccm" nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are {d,i}ccm.

Piotr Zięcik e4bd11b3f3 dts: Add information about system bus frequency to the dts
This commit adds a fixed clock node (representing clock driving
system bus). The added node is then referenced by peripherals requiring
information about driving clock frequency.

Kumar Gala 582e676248 dts: arc: emsk: Remove emsk_dt.h and CONFIG options from dtsi
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.

Kumar Gala 8d92653f26 dts: arc: emsk: Remove DT_APB_CLK_HZ from emsk_dt.h
As we want to remove emsk_dt.h we just fold the DT_APB_CLK_HZ into the
emsk.dtsi.

Kumar Gala 7feb430b38 dts: arc: emsk: Remove DT_{I,D}CCM_SIZE from emsk_dt.h
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

Kumar Gala 0eb0e78d67 dts: Fix warnings associated with reg/unit-address not matching
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.

Kumar Gala 325a9b3ea4 boards: arc: Convert boards to use device tree for LEDs & Buttons
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.

Kumar Gala 0ff2ae1fe8 dts: Cleanup warnings associated with interrupt controller nodes
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.
