When the compiler decides not to inline the Chunky-to-Planar core
functions, the build fails with:
c2p_planar.c:(.text+0xd6): undefined reference to `c2p_unsupported'
c2p_planar.c:(.text+0x1dc): undefined reference to `c2p_unsupported'
c2p_iplan2.c:(.text+0xc4): undefined reference to `c2p_unsupported'
c2p_iplan2.c:(.text+0x150): undefined reference to `c2p_unsupported'
Fix this by marking the functions __always_inline.
