perf, x86: Fix pre-defined cache-misses event for AMD family 15h cpus

With AMD cpu family 15h a unit mask was introduced for the Data Cache
Miss event (0x041/L1-dcache-load-misses). We need to enable bit 0
(first data cache miss or streaming store to a 64 B cache line) of
this mask to proper count data cache misses.

Now we set this bit for all families and models. In case a PMU does
not implement a unit mask for event 0x041 the bit is ignored.
