s390/boot: Add prefix filtering to bootdebug messages
Enhance boot debugging by allowing the "bootdebug" kernel parameter to
accept an optional comma-separated list of prefixes. Only debug messages
starting with these prefixes will be printed during boot. For example:
bootdebug=startup,vmem
Not specifying a filter for the "bootdebug" parameter prints all debug
messages. The `boot_fmt` macro can be defined to set a common prefix:
#define boot_fmt(fmt) "startup: " fmt
