[S390] vmcp cleanup
A number of small changes to vmcp: - Change preferred email address. - Use PRINT_xxx machros from debug.h like most s390 drivers, define "vmcp:" as PRINTK_HEADER and wrap error message at column 80. - Add error number to error message. - Update copyright, as I touched this file. - Small whitespace diff. - Use mutex instead of semaphore (Thanks Heiko for the patch) - Don't register debug feature on failure. - Check debug feature registration on init to avoid a potential oops on unload if the debug feature could not be registered--> 2 more messages.
