When going into DEEP_SLEEP state, the ARC timer
needs to be restored.
This implements the function to restore the timer
after sleep.
As the time spent during sleep is not currently known,
the timer is expired to reschedule the application task.

In order to resume the ARC from deep sleep,
the interrupts need to be restored.
The FIRQ stack needs to be saved and restored
when performing sleep operations.
During early initialization, the sp in the 2nd register bank
is made to refer to _firq_stack.
This allows for the FIRQ handler to use its own stack.
Fast Interrupts cannot be used after sleep if this information
is not restored.
This patch adds the suspend and resume functions.

Using a LIFO instead of a FIFO has the potential benefit that more
recently in-use buffers may be "cache-hot" and therefore accessed
faster than least recently used (which is what we get with a FIFO).

In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

This is only for use with custom destroy callbacks, so that the

Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu. Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom. Do not present pseudo generators if a true random generator
is presented.
This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.
In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.
Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".
This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:
NET_BUF_POOL_DEFINE(pool_name, ...);
Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.
This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

The existing explicit sys_rand32_init() function runs immediately after
