pmdomain: ti-sci: set the GENPD_FLAG_ACTIVE_WAKEUP flag for all PM domains

With this flag, if a device is marked on the wakeup path, the corresponding
PM domain is kept powered on.

This commit fixes the no_console_suspend support for some TI platforms
(tested on J7200). In case of no_console_suspend the serial core marks the
device on the wakeup path, but without this patch the power domain is
powered off anyway.
