rsa_verify() expects a memory region and wants to do the hashing itself, but there may be cases where the hashing is done via other means, like hashing a squashfs rootfs.

So add rsa_verify_hash() to allow verifiying a signature against an existing hash. As this entails the same verification routines we can just move the relevant code over from rsa_verify() and also call rsa_verify_hash() from there.

Applied to u-boot/master, thanks!
