MIPS: Sibyte: Fix Kconfig dependencies of SIBYTE_BUS_WATCHER

Commit 6793f55cbc84 ("MIPS: sibyte: Amend dependencies for
SIBYTE_BUS_WATCHER") changed the dependencies for
SIBYTE_BUS_WATCHER to make it visible only if SIBYTE_BCM112X
or SIBYTE_SB1250 are enabled.

In the code in arch/mips/sibyte/common/bus_watcher, however,
a #if defined() check suggests that this functionality should
also be available for SIBYTE_BCM1x55 and SIBYTE_BCM1x80.

Make it selectable by extending the dependencies of
SIBYTE_BUS_WATCHER in arch/mips/sibyte/Kconfig.
