crypto: atmel-aes - Fix CTR counter overflow when multiple fragments

Browse source

[ Upstream commit 3907ccfaec ]

The CTR transfer works in fragments of data of maximum 1 MByte because
of the 16 bit CTR counter embedded in the IP. Fix the CTR counter
overflow handling for messages larger than 1 MByte.
