This adds support for the SAM0 DMA Controller (DMAC). Chained
transfer are not currently implemented.
Tested with tests/drivers/dma/loop_transfer and custom modifications
to that test using three parallel reloading channels. Also tested
with a trivial program that did memory->serial.

While configure_linker_script() may be useful for other linkers, it
currently only aimed at GNU ld. To really be useful among different
linkers, we would need to abstract its usage of the C preprocessor.
We can do this later, if needed.

Rather than associating defines within the function, let the call sites
themselves pick the appropriate define. Add new argument for this.

Reduce the amount of {pre,post}fixing magic: I.e. let it be clearer at
call sites that "linker.cmd" is a file, rather than having to know that
"linker" will be postfixed with ".cmd" internally.
Change argument name to linker_script_gen, to better indicate that we
are producing a generated file.

Now that we avoid the two-step procedure, we can simplify the name of

Change construct_add_custom_command_for_linker_pass from function into
macro. The purpose of the function was to set the output variable to a
string that would be fed to add_custom_command. This meant all use
required a two-step procedure and an intermediate
variable (custom_command).
The environmental leakage from a macro in this case is small, so let's
just simplify to a macro and avoid the two-step.

This makes use of BT_GATT_SERVICE_DEFINE to statically define services

Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This reintroduces support for static service in the form of a new API,
BT_GATT_SERVICE_DEFINE, and changes the internal services (GAP/GATT)
to be defined as const as they are never register/unregistered.
Internal service needed to be renamed in order to keep the same order
as before since the section elements are sorted by name.

The PR removes the exclusive limit on enabling both UART_ASYNC_API
and UART_INTERRUPT_DRIVEN so that both options can be enabled
together for same uart driver.
Also, the interrupt handler will be used for both cases. So, enable
definition of interrupt handler for both.
However, nRF UART driver still wants to enable only one of them.
So, a new config is added to disable the code for UART_ASYNC_API
when the option UART_INTERRUPT_DRIVEN is enabled.

device_get_binding() compares pointers first before doing strcmp().
However, enabling coverage forces -O0 to disable any compiler
optimizations. There would be multiple copies of the same string,
and the code pathing doing pointer comparsion would not be tested
at all. So add this flag to merge string constants such that
the pointer comparison would be exercised.
This also adds a bad driver which fails initialization. This is
to make sure that execution path is covered.
