common/dpaax/caamflib: remove some inline keys
The space in descriptor buffer is scarce as it is limited to
64 words for platforms except ERA10 (which has 128).
As the descriptors are processed with QI, it adds some words
to the descriptor which is passed.
Some descriptors used for SDAP were using too much words reaching
the limit.
This patch reduces the number of words used by removing the inlining
of some keys (done for performance) in order to have working
descriptors.

common/dpaax/caamflib: support PDCP-SDAP
The SDAP is a protocol in the LTE stack on top of PDCP. It is
dedicated to QoS.
The difficulty of implementing this protocol is because the
PDCP change behavior regarding encryption and authentication
of the SDU it receives. In effect PDCP shall not encrypt the
SDAP SDU but must authenticate it (when encryption and
authentication is enabled).
The current version of SEC does not support the SDAP and the
change of behavior of PDCP prevent the use of the PDCP
protocol command available.
The way to do it is to reuse the PDCP implementation but to
not use the PDCP protocol and to have descriptors which
performs the PDCP protocol.
It is implemented by doing small changes of code:
#ifdef SDAP_SUPPORT
length += SDAP_BYTE_SIZE;
offset -= SDAP_BYTE_SIZE;
#endif
after having computed the size of the SN to read from the
input data, then
#ifdef SDAP_SUPPORT
MATHI(p, MATH0, LSHIFT, 8, MATH1, 8, 0);
MATHB(p, MATH1, AND, sn_mask, MATH1, 8, IFB | IMMED2);
#else
MATHB(p, MATH0, AND, sn_mask, MATH1, 8, IFB | IMMED2);
#endif
It will keep the SN and the SDAP header in MATH0, then shift
it to remove the SDAP header and store the result in MATH1.

The issue observed due to these JUMP command on LX2160 is that,
the CAAM gets stuck and the processing never get completed. The
system becomes unusable.
