[PATCH 4.9 20/63] MIPS: jazz: fix 64bit build

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

------------------

[ Upstream commit 41af167fbc0032f9d7562854f58114eaa9270336 ]

64bit JAZZ builds failed with

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