Introduce /sys/debug/kernel/diag_stat with a statistic how many diagnose
calls have been done by each CPU in the system.

Let's unify basic access to sclp fields by storing the data in an external
struct in asm/sclp.h.
The values can now directly be accessed by other components, so there is
no need for most accessor functions and external variables anymore.
The mtid, mtid_max and facility part will be cleaned up separately.

To provide access to the set-partition-resource-parameter interface
to user space add a new attribute to hypfs/debugfs:
* s390_hypsfs/diag_304
The data for the query-partition-resource-parameters command can
be access by a read on the attribute. All other diagnose 0x304
requests need to be submitted via ioctl with CAP_SYS_ADMIN rights.
