  Fix clang 11 inline asm constraint error when building powerpc GENERIC64
  kernels:
  
  sys/powerpc/aim/mmu_radix.c:728:19: error: invalid operand for inline asm constraint 'i'
          __asm __volatile(PPC_TLBIEL(%0, %1, %2, %3, 1)
                           ^
  sys/powerpc/aim/mmu_radix.c:149:3: note: expanded from macro 'PPC_TLBIEL'
           __XSTRING(.long PPC_INST_TLBIEL | \
           ^
  sys/sys/cdefs.h:161:22: note: expanded from macro '__XSTRING'
  #define __XSTRING(x)    __STRING(x)     /* expand x, then stringify */
                          ^
  sys/sys/cdefs.h:160:21: note: expanded from macro '__STRING'
  #define __STRING(x)     #x              /* stringify without expanding x */
                          ^
  <scratch space>:112:1: note: expanded from here
  ".long 0x7c000224 | (((%0) & 0x1f) << 11) | (((%1) & 0x1f) << 21) | (((%2) & 0x3) << 18) | (((%3) & 0x1) << 17) | (((1) & 0x1) << 16)"
  ^
  
  This is solved by making the affected inline functions __always_inline.
