The ARCv2 will provide support for nanokernel tickless idle.
The other architectures still have the MICROKERNEL dependency by having
the APM menu depend on MICROKERNEL.

TICKLESS_IDLE_THRESH depends on TICKLESS_IDLE, which depends on
ADVANCED_POWER_MANAGEMENT, which itself already depends on MICROKERNEL.
There is thus no point in having TICKLESS_IDLE_THRESH depend on
MICROKERNEL.

We want to be able to do fine-grained enabling of debug logs for the
various Bluetooth sub-modules. They all default to 'n' so an app
writer would need to go and enable the specific ones that they're
interested in.

The revised option name more accurately describes its purpose, and
avoids potential confusion with the microkernel's tickless idle
capability. Also, inverting the "polarity" of the option means that
conditional code that references it does not have to use negative
logic, which make the code easier to comprehend.

Revises the relationships between several configuration options
to support a tickless kernel capabilty. Specifically:
1) SYS_CLOCK_TICKS_PER_SEC is now always defined, so that it can
be referenced by TICKLESS_KERNEL. However, SYS_CLOCK_TICKS_PER_SEC
is forced to 0 when there is no timer interrupt support.
2) NUM_TIMER_PACKETS is now forced to 0 in a microkernel system
when TICKLESS_KERNEL is enabled.
3) TIMESLICING is now disabled when TICKLESS_KERNEL is enabled.

Allows the number of task priority levels supported by the micro-
kernel to be configured, rather than fixing this value at 64.
Setting NUM_TASK_PRIORITIES to N provides support for task
priorities 0 (highest priority) through N-1 (lowest priority).
The lowest priority is reserved for the kernel's idle task.
This enhancement allows system designers to significantly reduce
the size of the microkernel's task priority queues by eliminating
unneeded queues. In systems requiring only a few task priorities
over 500 bytes can be saved.

This patch adds a simple HCI UART (H4) driver that currently maps to
the second UART in the system. The main intention is to use this
together with qemu for accessing the Bluetooth controller available on
the host OS side.
The H4 HCI transport protocol is perhaps the simplest of the standard
HCI transports. It consists of a single byte in the beginning of each
packet which indicates the type of the packet: HCI event, HCI command,
ACL data, or SCO data (which we don't use at the moment).

will need to call to initialize Bluetooth functionality.
