[PATCH] dt-bindings: ath10k: fix qcom,coexist-support documentation

The driver is reading the value using the function
"of_property_read_u8", which is expecting the data to be
represented on 8 bits.
By default, the value specified in the DT is saved using a 32 bits
format, which cause the driver to read "0" instead of "1".
To make the driver work properly, the DT should specify the right
data representation to use.
