crypto: caam - don't hardcode inpentry size
Using dma_addr_t for elements of JobR input ring is not appropriate on
all 64-bit SoCs, some of which, like i.MX8MQ, use only 32-bit wide
pointers there. Convert all of the code to use explicit helper
function that can be later extended to support i.MX8MQ. No functional
change intended.
