Subject: [PATCH] gpio: sifive: Fix -Wint-to-pointer-cast warning
dev_read_addr() returns a value of type fdt_addr_t which is a 64-bit
address and plat->base is a pointer. In a 32-bit build, this causes the
following warning seen when building sifive-gpio.c:
warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
Change to use dev_read_addr_ptr().
