Subject: [PATCH] watchdog: mtx-1: drop au1000.h header file

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'? [-Werror=implicit-function-declaration]
  603 |  void __iomem *b = (void __iomem *)KSEG1ADDR(AU1000_SYS_PHYS_ADDR);
../arch/mips/include/asm/mach-au1x00/au1000.h:603:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
  603 |  void __iomem *b = (void __iomem *)KSEG1ADDR(AU1000_SYS_PHYS_ADDR);

Fixes: 04bf3b4f5fc0 ("[WATCHDOG] MTX-1 Watchdog driver")
