accel/ivpu/37xx: Fix interrupt_clear_with_0 WA initialization
Using PCI Device ID/Revision to initialize the interrupt_clear_with_0
workaround is problematic - there are many pre-production
steppings with different behavior, even with the same PCI ID/Revision
Instead of checking for PCI Device ID/Revision, check the VPU
buttress interrupt status register behavior - if this register
is not zero after writing 1s it means there register is RW
instead of RW1C and we need to enable the interrupt_clear_with_0
workaround.
Fixes: 7f34e01f77f8 ("accel/ivpu: Clear specific interrupt status bits on C0")
