i3c: master: dw-i3c-master: Fix OD_TIMING for spike filter

Browse Source 
Fix the I3C device with spike filter unable to detect issue by setting
tHIGH_INIT to 200ns for first broadcast address.
This is according to MIPI SPEC 1.1.1 for first broadcast address
which is already part of linux upstreamed patch.
