There are packet restrictions imposed by PHY update procedure
for PDU that includes CTE (BT Core 5.3 :
- central/peripheral can't send PDU with CTE after receive or send
LLPHY_UPDATE_IND until instant if the PHY after instant is CODED
- peripheral can't send PDU including CTE after it sends LL_PHY_REQ
PDU until receive LL_PHY_UPDATE_IND, LL_UNKNOWN_RSP, LL_REJECTED_EXT_-
IND_PDU if there is a CODE PHY in TX_PHYS
- peripheral can't send PDU including CTE after it sends LL_PHY_RSP
PDU until receive LL_PHY_UPDATE_IND if there is a CODED PHY in TX_PHYS
of LL_PHY_RSP PDU or RX_PHYS of LL_PHY_REQ PDU.
The BT 5.3 Core spec defines only one PDU that may include CTE, that is
LL_CTE_RSP PDU. To avoid a situation that there is such PDU enqueued
for transmission in LLL when packet transmission restrictions should
be applied, both procedures in almost all cases will not be executed
in parallel.
Current implementation always handles remote procedurerequest first.
There are possible three scenarios:
1. Remotely requested PHY update. Locally initiated CTE REQ.
In this case there is no problem with LL_CTE_RSP waiting in a TX
queue in LLL. Both procedures may be executed one after another.
2. Remotely requested CTE REQ. Locally initiated PHY update.
In this case the CTE REQ is handled first and it will pause the
PHY update procedure until LL_CTE_RSP PDU is acknowledged by
remote. Then the CTE REQ procedure will be completed and PHY update
continued.
3. Locally initiated PHY update is pending. Arrives remote CTE REQ.
In this case the CTE REQ will be paused until localy initiated PHY
update is completed. Then the CTE REQ will be continued.
Thanks to that there should be no PDU including CTE in LLL TX quueue.
That releases us from a situation there is a LL_CTE_RSP PDU in the
LLL TX qeueue that must be changed into LL_REJECT_EXT_IND PDU due to
change of PHY to CODED PHY after PHY update procedure completes.

In peripheral role when:
- data length update is enabled
- the CONFIG_BT_MAX_CONN is set to 1
the PHY update control procedure after reaching instant sends two
notifications to host. It notifies host about PHY update and data
length change. Both notifications are send one after another, so two
free node rx are required. The number of available node rx in
provided conditions is one. The PHY update FSM is stalled in waiting
state for enough empty node rx. At the same time remote device is
allowed to send new remote control procedures. Received request are
handled by PHY update FSM that asserts due to unknown procedure opcode.
The commit changes number of allocated nodes to be two times a number
of LLCP connections.
This is a workaround for the issue. The best solution seems to be
sharing nodsx between connections. Though this solution requires
buffering remote control procedures until host notification is done.

Macros responsible for preparation of packet configuration flags in
regard of PHY and CTE were wrong. PHY flags are not used as regular
integer values but bits in a bitfield, hence size of the field in
packet configuration flags is three instead of two.
In such case CTE presen filed should be moved to bit 4th.
The problem was spot when testing implementation with CODED PHY
enabled. When device was sending PDUs that had attached CTE the
radio was configured to use CODED PHY due to wrong bit set in
packet configuration flags variable (overlapping of CTE bit
with CODED PHY bit).

CTE type and length parameters in connected mode are dependent
on remote CTE request procedure. These parameters are required
to setup radio to correctly transmit CTE. The same parameters
are also included in CTEInfo byte of data channel PDU header.
The parameters were provided to LLL with PDU to be transmitted
and by lll_conn::df_tx_cfg, hence it was redundant.
The PDUs CTEInfo has to be set before transmission anyway.
The contents of the PDU are set in ULL by CTE RSP control
procedure. To remove redundancy CTE length and type from lll_df_-
conn_tx_cfg were removed from ll_df_conn_tx_cfg. It was better
option becuse it saves instructions in LLL.
Radio in connected mode was configured by lll_df_conn_cte_tx_enable.
The function just unpacked the lll_df_conn_tx_cfg mebmers and
called static function df_cte_tx_configure.
Instead of extending parameters list of lll_df_conn_cte_tx_enable,
the function was removed and df_cte_tx_configure was changed to
be global function - lll_df_cte_tx_configure.
Now LLL directly passes all parameters from pdu_data::cte_info
and ll_df_conn_tx_cfg to lll_df_cte_tx_configure.
