bluetooth: host: Interval is deprecated, use interval_us

With the introduction of Shorter Connection Intervals, Zephyr has
deprecated bt_conn_le_info.interval in favour of
bt_conn_le_info.interval_us. Changing the unit from 1.25 milliseconds to
microseconds.

applications/nrf_desktop/src/modules/ble_conn_params.c

 #define CONN_INTERVAL_BLE_REG		0x0008 /* 10 ms */
+ #define CONN_INTERVAL_BLE_US           10000
 #else
 #define CONN_INTERVAL_BLE_REG		0x0006 /* 7.5 ms */
+ #define CONN_INTERVAL_BLE_US           7500


Can we use BT_GAP_US_TO_CONN_INTERVAL macro instead of defining CONN_INTERVAL_BLE_REG macro? That would simplify implementation and got rid of redundant definitions.

Can i do that in a follow up pr? I would prefer not to delay this one

Sure, no problem
