[PATCH] hw/arm/pxa2xx: Add missing fallthrough comment

[Thomas Huth]

Let's make this file compilable with -Werror=implicit-fallthrough :
Looking at the code, it seems like the fallthrough is intended here,
so we should add the corresponding "/* fallthrough */" comment here.

Has it been sent to qemu-trivial? I don't find it in my folder.
