mfpmr() needs to be marked always inline, otherwise the compiler will
complain that the rn argument can't be passed to the asm block as an
integer:
arch/powerpc/include/asm/reg_fsl_emb.h:18:9: warning: 'asm' operand 1 probably does not match constraints
18 | asm (".machine push; "
| ^~~
arch/powerpc/include/asm/reg_fsl_emb.h:18:9: error: impossible constraint in 'asm'
Mark mtpmr() always inline also to avoid any future problems with it.
Fixes: f01dbd73cc ("powerpc/fsl: Modernise mt/mfpmr")
