wcnss: Enable/disable WCNSS register dump on WCNSS bite

When Apps recieves a WDOG bite from WCNSS, collecting a register
dump of WCNSS is helpful to root cause the failure. WCNSS may not
be properly clocked in some WCNSS bite cases, and that may
cause unclocked register access failures.  So add a feature flag
so that customers can disable this register dump on production
builds.
