Lukas Wunner cf97c5e0f7 xhci: Preserve RsvdP bits in ERSTBA register correctly
xhci_add_interrupter() erroneously preserves only the lowest 4 bits when
writing the ERSTBA register, not the lowest 6 bits.  Fix it.

Migrate the ERST_BASE_RSVDP macro to the modern GENMASK_ULL() syntax to
avoid a u64 cast.

This was previously fixed by commit 8c1cbec9db1a ("xhci: fix event ring
segment table related masks and variables in header"), but immediately
undone by commit b17a57f89f69 ("xhci: Refactor interrupter code for
initial multi interrupter support.").

Fixes: b17a57f89f69 ("xhci: Refactor interrupter code for initial multi interrupter support.")
