This patch moves complete nic tls offload (kTLS) code from crypto
directory to drivers/net/ethernet/chelsio/inline_crypto/ch_ktls
directory. nic TLS is made a separate ULD of cxgb4.

Current design enables ktls setting from start, which is not
efficient. Now the feature will be enabled when user demands
TLS offload on any interface.
v1->v2:
- taking ULD module refcount till any single connection exists.
- taking rtnl_lock() before clearing tls_devops.
v2->v3:
- cxgb4 is now registering to tlsdev_ops.
- module refcount inc/dec in chcr.
- refcount is only for connections.
- removed new code from cxgb_set_feature().
v3->v4:
- fixed warning message.

This patch contains handling of first part or middle part of the record.
When we get a middle record, we will fetch few already sent bytes to
make packet start 16 byte aligned.
And if the packet has only the header part, we don't need to send it for
packet encryption, send that packet as a plaintext.
v1->v2:
- un-necessary updating left variable.
v3->v4:
- replaced kfree_skb with dev_kfree_skb_any.

A new macro is defined to enable ktls tx offload support on Chelsio
T6 adapter. And if this macro is enabled, cxgb4 will send mailbox to
enable or disable ktls settings on HW.
In chcr, enabled tx offload flag in netdev and registered tls_dev_add
and tls_dev_del.
v1->v2:
- mark tcb state to close in tls_dev_del.
- u_ctx is now picked from adapter structure.
- clear atid in case of failure.
- corrected ULP_CRYPTO_KTLS_INLINE value.
v2->v3:
- add empty line after variable declaration.
- local variable declaration in reverse christmas tree ordering.
