/*******************************************************************************

 *

 * Function         BTM_ReadPowerMode

 *

 * Description      This returns the current mode for a specific

 *                  ACL connection.

 *

 * Input Param      remote_bda - device address of desired ACL connection

 *

 * Output Param     p_mode - address where the current mode is copied into.

 *                          BTM_ACL_MODE_NORMAL

 *                          BTM_ACL_MODE_HOLD

 *                          BTM_ACL_MODE_SNIFF

 *                          BTM_ACL_MODE_PARK

 *                          (valid only if return code is BTM_SUCCESS)

 *

 * Returns          true if successful, false otherwise
