crypto: stm32 - Use accelerated readsl/writesl

Browse source

When reading or writing crypto buffers the inner loops can
be replaced with readsl and writesl which will on ARM result
in a tight assembly loop, speeding up encryption/decryption
a little bit. This optimization was in the Ux500 driver so
let's carry it over to the STM32 driver.
