gdma: prevent mutli-channels connect to the same peripheral

Browse Source 
1. add check in the gdma driver, to prevent multiple channels connecting
   to the same peripheral
2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP
   targets (e.g. esp32c3/s3). We should search for a free one when
install async memcpy driver.
