This is not a conversion for endianess with respect to CPU but for command format of the device. It should always be performed regardless of platform.

In other words, it could be equivalent to:
value |= 0x03 << 6; // lower byte
value |= (addr & 0x3F00) >> 8; // lower byte
value |= (addr & 0xFF) << 8; //higher byte

We think the previous form is easier to read. Should we keep it or change to the later one?--

For many audio cards there need to add some off-CODEC widgets, and this
is hard to be supported by dts only, because maybe some widgets need one
or more call backs, such as wevent.
