ar7: fix kernel builds for compiler test

TI AR7 Watchdog Timer is only build for 32bit.

Avoid error like:
In file included from drivers/watchdog/ar7_wdt.c:29:
./arch/mips/include/asm/mach-ar7/ar7.h: In function ‘ar7_is_titan’:
./arch/mips/include/asm/mach-ar7/ar7.h:111:24: error: implicit declaration of function ‘KSEG1ADDR’; did you mean ‘CKSEG1ADDR’? [-Werror=implicit-function-declaration]
  111 |  return (readl((void *)KSEG1ADDR(AR7_REGS_GPIO + 0x24)) & 0xffff) ==
      |                        ^~~~~~~~~
      |                        CKSEG1ADDR
