clocksource: Use GENMASK_ULL in definition of CLOCKSOURCE_MASK
commit 0773cea37470f8e080c510fe720fc356cf35df3a upstream
Besides reusing existing code this removes the special case handling
for 64-bit masks, which causes clang to raise a shift count overflow
warning due to https://bugs.llvm.org//show_bug.cgi?id=10030.
