rtc: bd70528: fix driver dependencies
With CONFIG_BD70528_WATCHDOG=m, a built-in rtc driver cannot call
into the low-level functions that are part of the watchdog module:
drivers/rtc/rtc-bd70528.o: In function `bd70528_set_time':
rtc-bd70528.c:(.text+0x22c): undefined reference to `bd70528_wdt_lock'
rtc-bd70528.c:(.text+0x2a8): undefined reference to `bd70528_wdt_unlock'
drivers/rtc/rtc-bd70528.o: In function `bd70528_set_rtc_based_timers':
rtc-bd70528.c:(.text+0x50c): undefined reference to `bd70528_wdt_set'
Add a Kconfig dependency which forces RTC to be a module if watchdog is a
module. If watchdog is not compiled at all the stub functions for watchdog
control are used. compiling the RTC without watchdog is fine.
