The mtx-1_wdt driver does not need the au1000.h header file. Instead, the header file causes build errors, so drop it. This change fixes multiple build errors, all in au1000.h. E.g.: In file included from ../drivers/watchdog/mtx-1_wdt.c:44: ../arch/mips/include/asm/mach-au1x00/au1000.h: In function 'alchemy_rdsys': ../arch/mips/include/asm/mach-au1x00/au1000.h:603:36: error: implicit declaration of function 'KSEG1ADDR'; did you mean 'CKSEG1ADDR'?
