57879e772d feat(gdma): support channel allocator on esp32p4
There's two GDMA groups on ESP32P4, one is connected to AHB bus,
and another one is connected AXI bus.
We now have two seperate APIs for allocating DMA channels,
depends on the bus type.

dbca74f1ef gdma: prevent mutli-channels connect to the same peripheral
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.

Closes https://github.com/espressif/esp-idf/issues/10575
