habanalabs: zero pci counters packet
From: farah kassabri
In mmu debugfs node show un-scrambled physical addresses.
before read/write through data nodes, need to unscramble the
physical address before using it for pci transaction.

Currently hint address is ignored in case va block page size
is not power of 2. We need to support th user hint address also in this
case, but only if the hint address is aligned to page size.

Driver does not zero some pci counters packets before sending
to FW. This causes an out of sync PI/CI between driver and FW.

When device is removed, we need to make sure the F/W won't send us
any more events because during the remove process we disable the
interrupts.

it in the legacy 32-bit variable that the userspace reads to know the

between them, there won't be double release of already released
