crypto: amlogic - Remove kcalloc without check There is no real point in allocating dedicated memory for the irqs array. MAXFLOW is only 2, so it is easier to allocated the needed space directly within the 'meson_dev' structure. This saves some memory allocation and avoids an indirection when using the irqs array.

crypto: amlogic-gxl - permit async skcipher as fallback Even though the amlogic-gxl driver implements asynchronous versions of ecb(aes) and cbc(aes), the fallbacks it allocates are required to be synchronous. Given that SIMD based software implementations are usually asynchronous as well, even though they rarely complete asynchronously (this typically only happens in cases where the request was made from softirq context, while SIMD was already in use in the task context that it interrupted), these implementations are disregarded, and either the generic C version or another table based version implemented in assembler is selected instead. Since falling back to synchronous AES is not only a performance issue, but potentially a security issue as well (due to the fact that table based AES is not time invariant), let's fix this, by allocating an ordinary skcipher as the fallback, and invoke it with the completion routine that was given to the outer request.

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).
