dt-bindings: iio: temperature: ltc2983: describe broken mux delay property

Browse Source 
The 'adi,mux-delay-config-us' property is broken. It was supposed to
be in us, but the value is actually written directly to the register.
Describe the fact that it is broken and how it actually works.

Extra delay prior to each conversion, in addition to the internal 1ms

This property is supposed to be in microseconds, but to maintain
compatibility, this value will be multiplied by 100 before usage.
