Use the correct print format. Printing an unsigned int value should use %u
instead of %d. Otherwise printk() might end up displaying negative numbers.

Some controllers don't support the Simple Pairing Options feature that
can indicate the support for P-192 and P-256 public key validation.
However they might support the Microsoft vendor extension that can
indicate the validiation capability as well.

This adds logic to disable and reenable advertisement filters during
suspend and resume. After this patch, we would only receive packets from
devices in allow list during suspend.

Implements the feature to disable/enable the filter used for
advertising monitor on MSFT controller, effectively have the same
effect as "remove all monitors" and "add all previously removed
monitors".
This feature would be needed when suspending, where we would not want
to get packets from anything outside the allowlist. Note that the
integration with the suspending part is not included in this patch.

When the controller is powered off, the registered advertising monitor
is removed from the controller. This patch handles the re-registration
of those monitors when the power is on.

Enables advertising monitor offloading to the controller, if MSFT
extension is supported. The kernel won't adjust the monitor parameters
to match what the controller supports - that is the user space's
responsibility.
This patch only manages the addition of monitors. Monitor removal is
going to be handled by another patch.

Micrsoft defined a set for HCI vendor extensions. Check the following
link for details:

This provides the basic framework to enable the extension and read its
supported features. Drivers still have to declare support for this
extension before it can be utilized by the host stack.
