Cristian Stoica 86f80b5461 crypto: caam - remove duplicated sg copy functions 
commit 307fd543f3 upstream.

Replace equivalent (and partially incorrect) scatter-gather functions
with ones from crypto-API.

The replacement is motivated by page-faults in sg_copy_part triggered
by successive calls to crypto_hash_update. The following fault appears
after calling crypto_ahash_update twice, first with 13 and then
with 285 bytes:

Unable to handle kernel paging request for data at address 0x00000008
Faulting instruction address: 0xf9bf9a8c
