dma_addr_t might be different sizes depending on the configuration,
so we cannot print it as %llx:
drivers/misc/habanalabs/goya/goya.c: In function 'goya_sw_init':
drivers/misc/habanalabs/goya/goya.c:698:21: error: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]
Use the special %pad format string. This requires passing the
argument by reference.
Fixes: 2a51558c8c7f ("habanalabs: remove DMA mask hack for Goya")
