ARM64: crypto: add Crypto Extensions accelerated SHA implementation
This imports the Linux v6.3 state of the ARMv8 Crypto Extensions (CE)
accelerated SHA1/SHA2 routines. This increases hashing rate a tenfold:
sha1-generic: digest(7 bytes) = 11750ns digest(4097 bytes) = 59125ns
sha224-generic: digest(7 bytes) = 12750ns digest(4097 bytes) = 95000ns
sha256-generic: digest(7 bytes) = 2250ns digest(4097 bytes) = 94875ns
sha1-ce: digest(7 bytes) = 2875ns digest(4097 bytes) = 8125ns
sha224-ce: digest(7 bytes) = 3125ns digest(4097 bytes) = 7750ns
sha256-ce: digest(7 bytes) = 750ns digest(4097 bytes) = 7625ns
This shaves 400ms of a FIT image boot that uses sha256 as digest for
the images referenced by the selected configuration:
barebox@imx8mn-old:/ time bootm -d kernel-a
Dryrun. Aborted.
time: 998ms
barebox@imx8mn-new:/ time bootm -d kernel-a
Dryrun. Aborted.
time: 601ms
