    watchdog: Revert the AT91RM9200_WATCHDOG dependency
    
    Compiling the at91rm9200_wdt.c driver without at91rm9200
    support was leading to several errors:
    
    drivers/built-in.o: In function `at91_wdt_close':
    at91_adc.c:(.text+0xc9fe4): undefined reference to `at91_st_base'
    drivers/built-in.o: In function `at91_wdt_write':
    at91_adc.c:(.text+0xca004): undefined reference to `at91_st_base'
    drivers/built-in.o: In function `at91wdt_shutdown':
    at91_adc.c:(.text+0xca01c): undefined reference to `at91_st_base'
    drivers/built-in.o: In function `at91wdt_suspend':
    at91_adc.c:(.text+0xca038): undefined reference to `at91_st_base'
    drivers/built-in.o: In function `at91_wdt_open':
    at91_adc.c:(.text+0xca0cc): undefined reference to `at91_st_base'
    drivers/built-in.o:at91_adc.c:(.text+0xca2c8): more undefined references to
    `at91_st_base' follow
    
    So, reverting the modification of the "depends" Kconfig line
    introduced by patch a6a1bcd37 (watchdog: at91rm9200: add DT support)
    seems to be the good solution.
