[PATCH] crypto: inside-secure - fix unexported warnings

["Ben Dooks (Codethink)" <ben.dooks@codethink.co.uk>]

The safexcel_pci_remove, pcireg_rc and ofreg_rc are
not exported or declared externally so make them static.

This avoids the following sparse warnings:

drivers/crypto/inside-secure/safexcel.c:1760:6: warning: symbol 'safexcel_pci_remove' was not declared. Should it be static?
drivers/crypto/inside-secure/safexcel.c:1794:5: warning: symbol 'pcireg_rc' was not declared. Should it be static?
drivers/crypto/inside-secure/safexcel.c:1797:5: warning: symbol 'ofreg_rc' was not declared. Should it be static?
