facdb8b63baf56bc7c0ce2f16a32900866889f03 spapr_hcall: use spapr_ovec_* interfaces for CAS options
Currently we access individual bytes of an option vector via
ldub_phys() to test for the presence of a particular capability
within that byte. Currently this is only done for the "dynamic
reconfiguration memory" capability bit. If that bit is present,
we pass a boolean value to spapr_h_cas_compose_response()
to generate a modified device tree segment with the additional
properties required to enable this functionality.
As more capability bits are added, will would need to modify the
code to add additional option vector accesses and extend the
param list for spapr_h_cas_compose_response() to include similar
boolean values for these parameters.
Avoid this by switching to spapr_ovec_* helpers so we can do all
the parsing in one shot and then test for these additional bits
within spapr_h_cas_compose_response() directly.
