[PATCH v3 01/31] clk: mediatek: Use %pe to print errors

[Chen-Yu Tsai]

If %pe is used to print errors, a string representation of the error
would be printed instead of a number as with %ld. Also, all the sites
printing errors are deriving the error code from a pointer. Using %pe
is more straightforward.
