[CRYPTO] padlock: Remove pointless padlock module

When this is compiled in it is run too early to do anything useful:
[    6.052000] padlock: No VIA PadLock drivers have been loaded.
[    6.052000] padlock: Using VIA PadLock ACE for AES algorithm.
[    6.052000] padlock: Using VIA PadLock ACE for SHA1/SHA256 algorithms.

When it's a module it isn't doing anything special, the same functionality
can be provided in userspace by "probeall padlock padlock-aes padlock-sha"
in modules.conf if it is required.
