By default, CCC value is only stored to persistent memory during
BT disconnection. This commit adds an optional storing of CCC right
after it has been updated. This results in better robustness of
peripheral but increases system workqueue stack usage.

The channels assigned to the controller are reordered so that the ones
previously used and now available for other purposes have continuous
numbers. When the controller can take advantage of the pre-programmed
PPI channels (when TIMER0 is used as the event timer), the now free
channels are 0-4, when it cannot, it is the channel 0.

Several PPI channels in nRF5 family SoCs are pre-programmed with fixed
settings. A few of them can be used in the bluetooth controller instead
of the freely programmable ones that are used currently. This commit
makes such replacements where possible so that the universal channels
can be left available for other purposes.
This commit also removes macros used previously in calls to functions
enabling and disabling particular PPI channels (as it is sufficient
to use the BIT macro to set bits corresponding to the channel numbers)
to prevent such problems like the one introduces by commit
9d1ca9c390 (channel 18 changed to 17
but the related macro definition not updated).

In Bluetooth 5 the definition of LE security mode 1, has changed.
LE Security Mode 1 level 4 requires authenticated LE Secure Connections
pairing with encryption using a 128-bit strength encryption key.
This also changes the behaviour when a security request and response
would end up with a security level that is lower than the one requested.
Before pairing would complete, and the link would disconnect with error
authentication failure. Instead a SMP will abort pairing with error code
authentication requirement, or encryption key size.

The bluetooth controller has been using the flag '-Ofast' to keep
within a real-time limit. There are two problems with this; firstly,
when a project should be optimized for size it is standard to use -O2,
not -Ofast.
Secondly, optimization flags have been deemed to be non-portable, so
instead of directly using "-Ofast" we should use the intent-macro
OPTIMIZE_FOR_SPEED_FLAG to ensure toolchain portability.
Testing has shown that we are still within the real-time limit when
changing from -Ofast to -O2. -Ofast is about 1us and 1% faster, but
increases the code size by 13kB (5% of the available flash on a
nRF51).
Since the slowdown is comparatively small compared to the code size
increase we have decided to use -O2 in place of -Ofast.
Other optimization combinations were also measured and their results
can be seen below:
-Ofast in BLE Controller and in #pragma in entropy driver.
