[EGD-5706] Refactor creating audio device

Audio devices are created in the audio subsystem and it is not possible
to send a device to bt service upon creation.

Introduce hookable audio device factory to allow sharing bluetooth
audio device. Move audio devices from bsp to audio allowing removal of
unwanted bsp -> audio dependency.

Remove Bluetooth proxy device which turned out to be a dead end.

[EGD-5382] Add LowPower CpuSentinels

In order to synchronize the Low Power mode, the services were
immediately informed about the frequency change,
so that they can update their resources (e.g. PWM filling)
and services may request the maximum CPU frequency in order
to perform a task (e.g. screen redraw, telephone conversation)

[EGD-4977] Reduce audio lag during voice call

Reduce audio delay by reducing audio buffer size in router operation.
Audio streams are now created directly in the operations, not in the
audio service, which gives more flexibility.

Audio Buffer size is calculated based on endpoints (source, sink) and
operation capabilities. This commit also enables allocations in a
non-cacheable region of OCRAM for endpoints that use DMA for data
transport.

Introduce power-of-two operations that use built-in functions and
possibly dedicated hardware instructions of an MCU. These operations
are required by the audio stream buffer size calculation algorithm.
