Subject: [PATCH 1/6] dmaengine: jz4780: drop of_match_ptr from of_device_id table

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it is not relevant here).  This fixes
compile warning (!CONFIG_OF on x86_64):

    drivers/dma/dma-jz4780.c:1031:34: warning:
        ‘jz4780_dma_dt_match’ defined but not used [-Wunused-const-variable=]
