crypto: skcipher - remove support for physical address walks
Since the physical address support in skcipher_walk is not used anymore,
remove all the code associated with it. This includes:
- The skcipher_walk_async() and skcipher_walk_complete() functions;
- The SKCIPHER_WALK_PHYS flag and everything conditional on it;
- The buffers, phys, and virt.page fields in struct skcipher_walk;
- struct skcipher_walk_buffer.
As a result, skcipher_walk now just supports virtual addresses.
Physical address support in skcipher_walk is unneeded because drivers
that need physical addresses just use the scatterlists directly.
