crypto: amlogic - enable working on big endian kernel
On big endian kernel, the GXL crypto driver does not works.
This patch do the necessary modification to permit it to work on BE
kernel (removing bitfield and adds some cpu_to_le32).
Fixes: 48fe583fe541 ("crypto: amlogic - Add crypto accelerator for amlogic GXL")
