Move the DSB buffer handling to the display parent interface, making
display more independent of i915 and xe driver implementations.
Since the DSB parent interface is only called from intel_dsb.c, add the
wrappers there with smaller visibility instead of the usual
intel_parent.[ch], and using struct intel_dsb as the context parameter
for convenience.
Unfortunately, memset() being a macro in linux/fortify-string.h, we
can't use that as the function pointer name. dsb->memset() would be
using the macro and leading to build failures. Therefore, use .fill()
for the memset() functionality.
v2: s/memset/fill/
