s390/sclp: clean up, use sccb_mask_t where appropriate
Replace hardcoded instances where 32 or unsigned int (or long) is used
for SCLP event masks, and replace with sizeof(sccb_mask_t) and
sccb_mask_t respectively.
This improves readability and prepares for when we will increase
sccb_mask_t to 64 bits.
