Subject: [PATCH v2 5/6] arm64: dts: x1e80100-crd: fix wsa soundwire port
 mapping

Existing way of allocating ports dynamically is linear starting from 1 to
MAX_PORTS. This will not work for x1e80100 as the master ports are
are not mapped in the same order.

Without this fix only one speaker in a pair of speakers will function.

After this fix along with WSA codec changes both the speakers starts
working.
