s390/ctl_reg: mark __ctl_set_bit and __ctl_clear_bit as __always_inline

s390:tinyconfig fails to build with gcc 8.3.0.

arch/s390/include/asm/ctl_reg.h:62:2: note: in expansion of macro '__ctl_store'
  __ctl_store(reg, cr, cr);

Marking __ctl_set_bit and __ctl_clear_bit as __always_inline fixes the
problem.
