drm/xe/oa: Allow oa_exponent value of 0
[ Upstream commit 5bd566703e16b17d17f4fb648440d54f8967462c ]
OA exponent value of 0 is a valid value for periodic reports. Allow user
to pass 0 for the OA sampling interval since it gets converted to 2 gt
clock ticks.
v2: Update the check in xe_oa_stream_init as well (Ashutosh)
v3: Fix mi-rpc failure by setting default exponent to -1 (CI)
v4: Add the Fixes tag
Fixes: b6fd51c62119 ("drm/xe/oa/uapi: Define and parse OA stream properties")
