Application
- Add demo "ble_remote" into TC321X, which supports "TL_AUDIO_RCU_ADPCM_GATT_TELINK" audio mode.
- Add ble_controller demo.

Application
- Fix(TC321X): The flash information is not initialized normally when enabling macro "APP_FLASH_PROTECTION_ENABLE" and using Flash "P25Q80SU".
- Fix: Fix compile error when enabling macro "APP_BATT_CHECK_ENABLE".
PM
- Fix(TC321X): The MCU can not be waken up normally when using long suspend sleep mode.

Application
- Modify "USED_DEEP_ANA_REG" setting in "acl_c1p1_demo", "acl_peripheral_demo" and "acl_connection_demo".
