component/bt : decrease memory consumption by conn number 1. BLE only with 9(max) connection will decrease 3K DRAM 2. BR/EDR only with 7(max) connection will decrease 16K DRAM 3. Any of BLE or BR/EDR connection number decrease will also decrease DRAM consumption 4. Decrease one BLE connection will save about 1KB DRAM 5. Decrease one BR/EDR ACL connection will save about 1.2KB DRAM 6. Decrease one BR/EDR SCO/eSCO will save 2KB DRAM. 7. fix some definition and kconfig 8. remove 1.2k of vhci tx cache and make .bss & .data to heap about 1.4K 9. modify BT Reserved Memory size and modify example to support new bt kconfig 2018-06-15 09:40:51 -04:00			`CONFIG_BTDM_CONTROLLER_MODE_BLE_ONLY=`
