crypto: ux500 - fix incorrect kernel-doc comment syntax

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
There are certain files in drivers/crypto/ux500, which follow this syntax,
but the content inside does not comply with kernel-doc.
Such lines were probably not meant for kernel-doc parsing, but are parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warnings from kernel-doc.

E.g., presence of kernel-doc like comment in the header lines for
drivers/crypto/ux500/cryp/cryp.h at header causes this warning:

"warning: expecting prototype for ST(). Prototype was for _CRYP_H_() instead"

Similarly for other files too.

Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.
