Subject: [PATCH] crypto: x86/glue_helper make bool

Paul's changes to remove MODULE_LICENSE() out of the x86 glue_helper
causes a kernel with CONFIG_CRYPTO_GLUE_HELPER_X86=m to taint since
it now detects the license is missing if you try to build the driver
as a module, log below.

Fix this by removing the module option for it via Kconfig as it
cannot be a module.

glue_helper: module license 'unspecified' taints kernel.
glue_helper: module license 'unspecified' taints kernel.
