crypto: drivers - Switch back to struct platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/crypto to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

crypto: drivers - Drop sign/verify operations

The drivers aspeed-acry.c, hpre_crypto.c and jh7110-rsa.c purport to
implement sign/verify operations for raw (unpadded) "rsa".

But there is no such thing as message digests generally need to be
padded according to a predefined scheme (such as PSS or PKCS#1) to
match the size of the usually much larger RSA keys.

The bogus sign/verify operations defined by these drivers are never
called but block removal of sign/verify from akcipher_alg. Drop them.
