crypto: ccp - Add support for PCI device 0x17E0
PCI device 0x17E0 includes new TEE offsets, doesn't support a platform mailbox, and does support platform doorbell so introduce a new structure to represent it. Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
