crypto: ixp4xx - fix building wiht 64-bit dma_addr_t
The crypt_ctl structure must be exactly 64 bytes long to work correctly,
and it has to be a power-of-two size to allow turning the
64-bit division in crypt_phys2virt() into a shift operation, avoiding
the link failure:
ERROR: modpost: "__aeabi_uldivmod" [drivers/crypto/intel/ixp4xx/ixp4xx_crypto.ko] undefined!
The failure now shows up because the driver is available for compile
testing after the move, and a previous fix turned the more descriptive
BUILD_BUG_ON() into a link error.
Change the variably-sized dma_addr_t into the expected 'u32' type that is
needed for the hardware, and reinstate the size check for all 32-bit
architectures to simplify debugging if it hits again.
