powerpc/mm: mark more tlb functions as __always_inline
With CONFIG_OPTIMIZE_INLINING enabled, Laura Abbott reported error
with gcc 9.1.1:
arch/powerpc/mm/book3s64/radix_tlb.c: In function '_tlbiel_pid':
arch/powerpc/mm/book3s64/radix_tlb.c:104:2: warning: asm operand 3 probably doesn't match constraints
104 | asm volatile(PPC_TLBIEL(%0, %4, %3, %2, %1)
| ^~~
arch/powerpc/mm/book3s64/radix_tlb.c:104:2: error: impossible constraint in 'asm'
Fixing _tlbiel_pid() is enough to address the warning above, but I
inlined more functions to fix all potential issues.
To meet the "i" (immediate) constraint for the asm operands, functions
propagating "ric" must be always inlined.
