CHROMIUM: bluetooth: set advertising intervals

This patch supports specification of advertising intervals in
bluetooth kernel subsystem.

A new set_advertising_intervals mgmt handler is added to support
the new mgmt opcode MGMT_OP_SET_ADVERTISING_INTERVALS. The
min_interval and max_interval are simply recorded in hdev struct.

The intervals together with other advertising parameters would be
sent to the controller before advertising is enabled in the procedure
of registering an advertisement.

In cases that advertising has been enabled before
set_advertising_intervals is invoked, it would re-enable advertising
to make the intervals take effect. This is less preferable since
bluetooth core specification states that the parameters should be set
before advertising is enabled. However, the advertising re-enabling
feature is kept since it might be useful in multi-advertisements.
