crypto: caam: Avoid unused imx8m_machine_match variable

Browse Source 
If caam module is built without OF support, the compiler returns the
following warning:

	drivers/crypto/caam/ctrl.c:83:34: warning: 'imx8m_machine_match' defined but not used [-Wunused-const-variable=]

imx8m_machine_match is only referenced by of_match_node(), which is set
to NULL if CONFIG_OF is not set, as of commit 5762c20593 ("dt: Add
empty of_match_node() macro"):

	#define of_match_node(_matches, _node)  NULL

Do not create imx8m_machine_match if CONFIG_OF is not set.
