As the first argument of gf_write64() was of type unsigned long, and as some calls to gf_write64() were casting the first argument from void * to u64 the compiler and/or sparse were printing warnings for casts of wrong sizes when compiling for i386. This patch changes the type of the first argument of gf_write64() to const void *, and update calls to the function. This change fixed the warnings and allowed to remove casts from 3 calls to gf_write64(). In addition gf_write64() was renamed to gf_write_ptr() as the name was misleading because it only writes 32 bits on 32 bit systems. gf_write_dma_addr() was added to handle dma_addr_t values which is used at drivers/staging/goldfish/goldfish_audio.c.
