clk: 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 pd->va is a pointer. In a 32-bit build, this causes the
following warning seen when building sifive-prci.c:

  warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Change to use dev_read_addr_ptr().
