crypto: ccp - drop platform ifdef checks 

[ Upstream commit 42c2d7d02977ef09d434b1f5b354f5bc6c1027ab ]

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.

Fixes: 6c50634340 ("crypto: ccp - Add ACPI support")
