Subject: [PATCH] mt76: mt7603: disable merge of OTP ROM data by default
Git-commit: 6d3390a664bbac544d1656503a3ccf947f154770
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430
The reference driver does not seem to enable it by default, only under certain
conditions, e.g. when a .bin file is loaded.
Make it opt-in via a device tree property for now, in case it is needed on some
boards.
