The Bluetooth configurations use the 24.576Mhz Cardinal Clock as clock source for ACE1.5, configured via the new "clock_source" parameter. Set BT_MCLK correctly for these platforms. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>
Add a comment that "clock_source" link configuration must be compatible with BT_MCLK. The current generic definition hard codes BT clock source to 1. This definition is ignored on older platforms, and on newer platforms it maps to same 24.576Mhz Cardinal Clock. This sets different constraints on BT_MCLK depending on the target platform.

Fix a bug in clock definitions for BT offload configurations. The BT_MCLK and link_control.clock_source definitions must match and this has not been the case for all ACE1.5+ scenarios.
The practical impacts are limited as this does not impact the common HFP NB/WB configuration, as the DSP is not the clock provider in these cases.
Impacts can be seen on ACE1.5+ with A2DP offload and BT HFP LBM test mode. Result is incorrect playback/capture speed.
