From: Fiona Trahe <fiona.trahe@intel.com>

Move all code into appropriate files, no actual code changes. Specifically:
 - Rename rte_qat_cryptodev.c to qat_sym_pmd.c
 - Create qat_sym_pmd.h and populate with fn prototypes for qat_sym_pmd.c
 - Create qat_comp_pmd.c/.h and populate with placeholder functions
 - Create qat_asym_pmd.c/.h and populate with placeholder functions
 - Rename qat_crypto_capabilities.h to qat_sym_capabilities.h
 - Move CRYPTODEV_NAME_QAT_SYM_PMD from qat_common.h to qat_sym_pmd.h
 - Move qat_sym_dev_private from qat_device.h to qat_sym_pmd.h
 - Move prototype for qat_sym_dev_info_get frm qat_device.h 2 qat_sym_pmd.h
 - Move all qat_device.c sym dev_ops fns to qat_sym_pmd.c file
 - Move all qat_sym.c dev_ops fns to qat_sym_pmd.c file
 - Remove unused header file #includes from all files.
 - Move pci_id_qat_map, probe/release/register from
   rte_qat_cryptodev.c to qat_device.c
 - Moved stray comment for bpi_cipher_ctx_init() from qat_sym.c
   to qat_sym_session.c
 - Changed all files to use SPDX license header
