Current driver uses static LMTST region allocated by firmware.
Firmware allocated memory for LMTST is available in PF/VF BAR2.
Using this memory have performance impact as this is mapped as
device memory. There is another option to allocate contiguous
memory at run time and map this in LMT MAP table with the
help of AF driver. With this patch dynamic allocated memory
is used for LMTST.
Also add myself as maintainer for crypto octeontx2 driver

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Provide an option in Inline IPsec configure mailbox to configure the
CPT_AF_LFX_CTL:CTX_ILEN for inline CPT LF attached to CPT RVU PF.
This is needed to set the ctx ilen to size of inbound SA for
HW errata IPBUCPT-38756. Not setting this would lead to new context's
not being fetched.
Also set FLR_FLUSH in CPT_LF_CTX_CTL for CPT LF's as workaround
for same errata.

This patch fixes following cleanup issues:
- Missing instruction queue free on cleanup. This
will lead to memory leak.
- lfs->lfs_num is set to zero before cleanup, which
will lead to improper cleanup.

On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF)
handles resource allocation and configuration for PFs and their VFs.
PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a
mailbox region. The PF then forwards these messages to the AF.
This patch adds code to configure inline-IPsec HW resources for
CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

cn10k_cpt.o, otx2_cptlf.o and otx2_cpt_mbox_common.o are linked
into both rvu_cptpf and rvu_cptvf modules:
> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> cn10k_cpt.o is added to multiple modules: rvu_cptpf rvu_cptvf
> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> otx2_cptlf.o is added to multiple modules: rvu_cptpf rvu_cptvf
> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> otx2_cpt_mbox_common.o is added to multiple modules: rvu_cptpf rvu_cptvf
Despite they're build under the same Kconfig option
(CONFIG_CRYPTO_DEV_OCTEONTX2_CPT), it's better do link the common
code into a standalone module and export the shared functions. Under
certain circumstances, this can lead to the same situation as fixed
by commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects").
Plus, those three common object files are relatively big to duplicate
them several times.
Introduce the new module, rvu_cptcommon, to provide the common
functions to both modules.

When CONFIG_CPUMASK_OFFSTACK is disabled, clang reports a warning
about a bogus condition:
drivers/crypto/marvell/octeontx2/otx2_cptlf.c:334:21: error: address of array 'lfs->lf[slot].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
if (lfs->lf[slot].affinity_mask)
~~ ~~~~~~~~~~~~~~^~~~~~~~~~~~~
In this configuration, the free_cpumask_var() function does nothing,
so the condition could be skipped.
When the option is enabled, there is no warning, but the check
is also redundant because free_cpumask_var() falls back to kfree(),
which is documented as ignoring NULL pointers.
Remove the check to avoid the warning.

CPT RVU Local Functions(LFs) needs to be attached to the
PF/VF to submit the instructions to CPT.
This patch adds the interface to initialize and attach
the LFs. It also adds interface to register the LF's
interrupts.
