drm/radeon/kms/igp: fix possible divide by 0 in bandwidth code (v2)
Some IGP systems specify the system memory clock in the Firmware table rather than the IGP info table. Check both and make sure we have a value system memory clock value. v2: make sure rs690_pm_info is called on rs780/rs880 as well. fixes a regression since 07d4190327b02ab3aaad25a2d168f79d92e8f8c2.
