[Skiboot] [PATCH v2] opal-prd: hservice: Enable hservice->wakeup() in BMC

This patch enables HBRT to use HYP special wakeup register in openBMC
which until now was only used in FSP based machines.
This patch also adds a capability check for opal-prd so that HBRT can
decide if the host special wakeup register can be used.
Fixes: 49999302251b("opal-prd: Add support for runtime OCC reset in ZZ")
