Piotr Mienkowski bca692ee8c drivers: i2c_gecko: use DT_<COMPAT>_<INSTANCE>_<PROP> defines
Use the new DT_<COMPAT>_<INSTANCE>_<PROP> defines to instantiate
devices. This commit adds also ability to define individual pin
locations on SoC series that support the feature. Definitions of GPIO
pins assigned to a given location have been moved from soc_pinmap.h file
to board DTS file.

Piotr Mienkowski 8bed2d5e27 soc: silabs_exx32: Add SWO logger support
By default, after reset SWO signal is not connected to GPIO pin. This
commit adds required initialization code to enable support for SWO
logger. Not all SoC series support the feature.

Piotr Mienkowski 973af2c8d7 dts: silabs: use 'aliases' to remove dts_fixup defines
By adding 'aliases' node in SoC .dtsi file it is possible to generate
DT_ defines which specify a logical name rather than relay on module
location on APB bus. E.g. DT_SILABS_GECKO_USART_40010000_LABEL becomes
DT_SILABS_GECKO_USART_USART_0_LABEL. Thus it is possible to remove
dts_fixup.h defines.

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 def322fe6d dts: Cleanup warnings associated with cpu node
When we fixed the missing reg property in the cpu node, we forgot to
add #address-cells & #size-cells for the node.

This fix the following warnings we get:
	Warning (reg_format): "reg" property in /cpus/cpu@0 has invalid
	length (4 bytes) (#address-cells == 2, #size-cells == 1)

Kumar Gala 6856ad1423 dts: Cleanup warnings associated with flash and memory nodes
We get several warnings of the form:

	Warning (unit_address_vs_reg): /flash: node has a reg or ranges
	property, but no unit name

or

	Warning (unit_address_vs_reg): /memory: node has a reg or ranges
	property, but no unit name

Fix by adding unit address that is missing to flash & memory nodes.
Additionally the Silabs memory nodes didn't have a compatiable or
device_type, so add those properties as well.
