of: add 'const' for of_property_*_string*() parameter '*np'
The of_property_{read,count,match}_string* family of functions never modify the struct device_node pointer that is passed in, so there is no reason for it to be non-const. Equivalent functions for all other types already take a 'const struct device_node *np'. Signed-off-by: David Rivshin <drivshin@allworx.com> Signed-off-by: Rob Herring <robh@kernel.org>
