crypto: ccp - Have it depend on AMD_IOMMU
sev-dev.c calls code in the AMD IOMMU now but that can't really work if
latter is not enabled in Kconfig:
ld: vmlinux.o: in function `__sev_firmware_shutdown.isra.0':
sev-dev.c:(.text+0x2501f0e): undefined reference to `amd_iommu_snp_disable'
ld: vmlinux.o: in function `snp_rmptable_init':
sev.c:(.init.text+0x26260): undefined reference to `amd_iommu_snp_en'
make[2]: *** [scripts/Makefile.vmlinux:37: vmlinux] Error 1
make: *** [Makefile:240: __sub-make] Error 2
Fix those deps.
