[ Upstream commit 504c28c853ec5c626900b914b5833daf0581a344 ]

Change the driver to use portable integer types to avoid
warnings during compile testing:

drivers/net/wan/ixp4xx_hss.c:863:21: error: cast to 'u32 *' (aka 'unsigned int *') from smaller integer type 'int' [-Werror,-Wint-to-pointer-cast]
        memcpy_swab32(mem, (u32 *)((int)skb->data & ~3), bytes / 4);
                           ^
drivers/net/wan/ixp4xx_hss.c:979:12: error: incompatible pointer types passing 'u32 *' (aka 'unsigned int *') to parameter of type 'dma_addr_t *' (aka 'unsigned long long *') [-Werror,-Wincompatible-pointer-types]
                                              &port->desc_tab_phys)))
                                              ^~~~~~~~~~~~~~~~~~~~
include/linux/dmapool.h:27:20: note: passing argument to parameter 'handle' here
                     dma_addr_t *handle);
                                 ^
