crypto: ccp - drop platform ifdef checks

When both ACPI and OF are disabled, the dev_vdata variable is unused:

drivers/crypto/ccp/sp-platform.c:33:34: error: unused variable 'dev_vdata' [-Werror,-Wunused-const-variable]

This is not a useful configuration, and there is not much point in saving
a few bytes when only one of the two is enabled, so just remove all
these ifdef checks and rely on of_match_node() and acpi_match_device()
returning NULL when these subsystems are disabled.
