Currently, the driver supports the Display Engine found in Mali DP500, DP550

This patch introduces z3fold, a special purpose allocator for storing
compressed pages. It is designed to store up to three compressed pages per
physical page. It is a ZBUD derivative which allows for higher compression
ratio keeping the simplicity and determinism of its predecessor.

The ThunderX SOC uses the same i2c block as the Octeon SOC.
The main difference is that on ThunderX the device is a PCI device
so device probing is done via PCI, interrupts are MSIX and the
clock is taken from device tree.

There is a race between the TWSI interrupt and the condition
that is required before proceeding:
Low-level: interrupt flag bit must be set
High-level controller: valid bit must be clear
If the interrupt comes too early and the condition is not met
the wait will time out, and t
The register offsets are different between Octeon and ThunderX so move
them into the algorithm struct and get rid of the define.

CN3860 does not interrupt the CPU when the i2c status changes. If
we get a timeout, and see the status has in fact changed, we know we
have this problem, and drop back to polling.

for a zero length message. The hardware does not support SMBUS QUICK
messages so disable the support and remove the zero length check.

Hi Wolfram,
v7 implements the changes from your review plus some comments from David.
I've moved the flush writeq patch before the HLC patch, because it is
already needed there and seems quite trivial and I've added a new patch
to disable the SMBUS QUICK support as discussed.
