[PATCH][next] PCI: rcar-gen2: Use fallthrough pseudo-keyword

[Gustavo A. R. Silva]

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Which unnecessary marking is being removed?
I don't see any.

There is none. I will remove those lines and send v2 with a URL
to the proper documentation for Linux v5.7 instead of 'lastest',
see:

https://www.kernel.org/doc/html/v5.7/process/deprecated.html?highlight=fallthrough#implicit-switch-case-fall-through

I'll add your Reviewed-by tag. :)
