habanalabs: Replace zero-length arrays with flexible-array members
Zero-length arrays are deprecated[1] and we are moving towards
adopting C99 flexible-array members instead. So, replace zero-length
arrays in a couple of structures with flex-array members.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [2].

habanalabs/gaudi2: avoid reconfiguring the same PB registers
It appears that, within the sync manager security configuration,
we reconfigure PB registers over and over without any need to do that.

habanalabs: add uapi to flush inbound HBM transactions
When doing p2p with a NIC device, the NIC needs to make sure all the
writes to the HBM (through the PCI bar of the Gaudi device) were
flushed.
habanalabs: add uapi to flush inbound HBM transactions
When doing p2p with a NIC device, the NIC needs to make sure all the
writes to the HBM (through the PCI bar of the Gaudi device) were
flushed.
It can be done by either the NIC or the host reading through the PCI
bar.
To support the host side, we supply a simple uapi to perform this flush
through the driver, because the user can't create such a transaction
by itself (the PCI bar isn't exposed to normal users).
