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

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

[Ben Dooks (Codethink)]

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?

Actually those variables have already disappeared from the 
cryptodev tree due to an earlier patch by Arnd.
So this patch won't apply anyway.

I'll see if I can spin a patch that makes safexcel_pci_remove
static.
