Subject: USB: xhci: fix 'broken_suspend' placement in struct xchi_hcd
Git-commit: 2419f30a4a4fcaa5f35111563b4c61f1b2b26841
Patch-mainline: v4.20
References: git-fixes

As commented in the struct's definition there shouldn't be anything
underneath its 'priv[0]' member as it would break some macros.

The patch converts the broken_suspend into a bit-field and relocates it
next to to the rest of bit-fields.

Fixes: a7d57abcc8a5 ("xhci: workaround CSS timeout on AMD SNPS 3.0 xHC")
