640035a2dc crypto: zip - Add ThunderX ZIP driver core
Add a driver for the ZIP engine found on Cavium ThunderX SOCs.
The ZIP engine supports hardware accelerated compression and
decompression. It includes 2 independent ZIP cores and supports:

- DEFLATE compression and decompression (RFC 1951)
- LZS compression and decompression (RFC 2395 and ANSI X3.241-1994)
- ADLER32 and CRC32 checksums for ZLIB (RFC 1950) and GZIP (RFC 1952)

The ZIP engine is presented as a PCI device. It supports DMA and
scatter-gather.

d80388eca1 crypto: cavium - fix leak on curr if curr->head fails to be allocated
The exit path when curr->head cannot be allocated fails to kfree the
earlier allocated curr.  Fix this by kfree'ing it.

15c0b9edcc crypto: cavium - switch to pci_alloc_irq_vectors
pci_enable_msix has been long deprecated, but this driver adds a new
instance.  Convert it to pci_alloc_irq_vectors and greatly simplify
the code, and make sure the prope code properly unwinds.

eafa26696a crypto: cavium - fix Kconfig dependencies
The driver fails to build if MSI support is disabled:

In file included from /git/arm-soc/drivers/crypto/cavium/cpt/cptpf_main.c:18:0:
drivers/crypto/cavium/cpt/cptpf.h:57:20: error: array type has incomplete element type 'struct msix_entry'
  struct msix_entry msix_entries[CPT_PF_MSIX_VECTORS];
                    ^~~~~~~~~~~~
drivers/crypto/cavium/cpt/cptpf_main.c: In function 'cpt_enable_msix':
drivers/crypto/cavium/cpt/cptpf_main.c:344:8: error: implicit declaration of function 'pci_enable_msix';did you mean 'cpt_enable_msix'? [-Werror=implicit-function-declaration]

On the other hand, it doesn't seem to have any build dependency on ARCH_THUNDER,
so let's allow compile-testing to catch this kind of problem more easily.
The 64-bit dependency is needed for the use of readq/writeq.
