Thomas Richter 2c14f49916 s390/cpumf: support user space events for counting 
[ Upstream commit 91d5364dc673fa9cf3a5b7b30cf33c70803eb3a4 ]

CPU Measurement counting facility events PROBLEM_STATE_CPU_CYCLES(32)
and PROBLEM_STATE_INSTRUCTIONS(33) are valid events. However the device
driver returns error -EOPNOTSUPP when these event are to be installed.

Fix this and allow installation of events PROBLEM_STATE_CPU_CYCLES,
PROBLEM_STATE_CPU_CYCLES:u, PROBLEM_STATE_INSTRUCTIONS and
PROBLEM_STATE_INSTRUCTIONS:u.
Kernel space counting only is still not supported by s390.
