s390/zcrypt: Support up to 256 crypto adapters.
There was an artificial restriction on the card/adapter id to only 6 bits but all the AP commands do support adapter ids with 8 bit. This patch removes this restriction to 64 adapters and now up to 256 adapter can get addressed. Some of the ioctl calls work on the max number of cards possible (which was 64). These ioctls are now deprecated but still supported. All the defines, structs and ioctl interface declarations have been kept for compabibility. There are now new ioctls (and defines for these) with an additional '2' appended which provide the extended versions with 256 cards supported.
