When the compiler decides not to inline the Chunky-to-Planar core

Fix this by marking the functions __always_inline.
While this could be triggered before by manually enabling both
CONFIG_OPTIMIZE_INLINING and CONFIG_CC_OPTIMIZE_FOR_SIZE, it was exposed
in the m68k defconfig by commit ac7c3e4ff401b304 ("compiler: enable
CONFIG_OPTIMIZE_INLINING forcibly").
Fixes: 9012d011660ea5cf ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

This is a fix for v5.4-rc1.
Can you please apply this for v5.4?
This is one of the 4 remaining build regressions, compared to v5.3.
Thanks!
v2:
- Add Reviewed-by,
- Fix Fixes,
- Add more explanation.
