4.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 41af167fbc0032f9d7562854f58114eaa9270336 ]
64bit JAZZ builds failed with
linux-next/arch/mips/jazz/jazzdma.c: In function `vdma_init`:
/linux-next/arch/mips/jazz/jazzdma.c:77:30: error: implicit declaration

Using correct casts and CKSEG1ADDR when dealing with the pgtbl setup
fixes this.
