bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

73483094da bluetooth: controller: nrf5: simplify preprocessor conditionals
We make a minor simplification in the way we define
RADIO_PDU_LEN_MAX in Nordic nRF LE radio driver; as
nRF51 SoC series is the only series where the LL PDU
max length representation is limited to a 5-bit field,
we simplify the conditional preprocessor expression,
to avoid having to list all nRF5x SoCs with PDU LEN
MAX is represented by an 8-bit integer field.

In addition, we modify the preprocessor conditional,
that compiles in the CCM support for 8-bit length field,
PDUs to be an #ifndef CONFIG_SOC_SERIES_NRF51X, instead
of #ifdef CONFIG_SOC_COMPATIBLE_NRF52X; this will
simplify the expression when adding nRF53X series
support.

aa38b2298c Bluetooth: controller: split: Fix for Tx Buffer Overflow error
When more than one simultaneous connections are active,
transmitting data packets to peer, a termination causes
host to use the flushed pending number of completed packets
count for other active connections. This is on reception
of HCI disconnection complete event. But the controller has
not yet released any of the pending enqueued Tx buffers
which was happening after the disconnection event was
dispatched to HCI layer.

The fix here is to dispatch the disconnection complete event
from the LLL context after pending Tx buffers have been
flushed and the buffers get returned to Tx pool in the ULL
context. This way buffers are in the Tx pool before host
get to process the disconnection complete event.
