feat: add support for SP805 Trusted watchdog module helper APIs
We leverage this module to generate secure interrupts which we
plan to use for exercising secure interrupt handling support in
SPM(Hafnium) in co-ordination with Cactus SP
Correspondingly, a device region node is added to the Cactus primary
SP manifest which captures the base address as well as other related
properties such as interrupts.
