[dpdk-dev] [PATCH] crypto/octeontx: fix global variable multiple definitions

[Anoob Joseph]

'cpt_logtype' & 'otx_cryptodev_driver_id' global variables are defined
in a header file which was causing multiple definitions of the
variables. Fixed it by moving the required vars to the .c file and
introducing a new macro so the CPT_LOG macros in common/cpt would use
the associated PMD log var.

Issue has been detected by '-fno-common' gcc flag.
