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+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.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.
