Bluetooth: Change page scan interval in fast connectable mode

This patch is based on a user space (hciops) patch which never made it
upstream but does make sense to include in the mgmt part of the kernel.

(User space) commit message from Dmitriy Paliy:
"
Page scan interval in fast connectable mode is changed from 22.5 msec to
160 msec to perform less aggressive page scanning. This is done
accordingly to controller vendor recommendation.

Primary concern is that current parameters 22.5 interval, 11.25 window,
and interleaved scanning occupy whole radio bandwidth. Changing interval
to 160 msec should be sufficient for both speeding up connection

Bluetooth: Use tx window from config response for ack timing

This change addresses an L2CAP ERTM throughput problem when a remote
device does not fully utilize the available transmit window.

The L2CAP ERTM transmit window size determines the maximum number of
unacked frames that may be outstanding at any time. It is configured
separately for each direction of an ERTM connection. Each side sends a
configuration request with a tx_win field indicating how many unacked
frames it is capable of receiving before sending an ack. The
configuration response's tx_win field shows how many frames the
transmitter will actually send before waiting for an ack.

It's important to trace both the actual transmit window (to check for
validity of incoming frames) and the number of frames that the
transmitter will send before waiting (to send acks at the appropriate
time). Now there are separate tx_win and ack_win values. ack_win is
updated based on configuration responses, and is used to determine
when acks are sent.

This patch changes the default MTU value for L2CAP ATT fixed channel

Differently from others L2CAP channels, in L2CAP ATT fixed channel

the L2CAP implementation. The only restriction in L2CAP spec is the
MTU value must not be less than 23 octets.

At ATT protocol level (on top of L2CAP), we have the ATT_MTU which
defines the maximum size of any ATT message sent between client and
server. GATT profile defines ATT_MTU default value to 23 octets. If
a GATT based profile wants to use ATT_MTU greater than 23 octets
(e.g. HID over GATT profile), it should negotiate a new value by
executing the GATT Exchange MTU sub-procedure.

Thus, in order to support any value of ATT_MTU negotiated at ATT
protocol level, our L2CAP implementation should have L2CAP ATT
fixed channel MTU equal or greater than ATT_MAX_MTU (512 octets).
