Use the device tree to assign the correct peripheral clock to each
UART/USART/LEUART. Previously, the clock identifier was determined
through the sequence number of the instantiated UART. This meant
configuring all UARTs when only one of the later UARTs was required.

The true mmio-sram nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are SRAM.

This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:
- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
in order to configure USB clock source.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

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.

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.

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)

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.

To move forward and remove use of Kconfig in dts files lets just create
SoC specific dtsi files that the boards can include. This lets us
remove:

CONFIG_SOC_PART_NUMBER_EFR32FG1P133F256GM48
