[PATCH v2 1/2] dma: ti: k3-udma: fix dma_addr_t typecasts

[Anshul Dalal]

With the change to dma_addr_t from u32 to u64 in the next patch, the
existing typecasts from void* to int or vice-versa will cause the
compiler to throw a "cast from pointer to integer of different size".

Therefore this patch changes the casts to a uintptr_t which is
guaranteed to hold a pointer value on the given arch, thus preventing
the compiler warning when enabling DMA_ADDR_T_64BIT for the R5 SPL.
