serial: s5p: Fix clk_get_by_index() error code check
clk_get_by_index() returns negative number on error. Assigning it to
unsigned int makes the subsequent "ret < 0" check always false, leading
in turn to possible unhandled errors. Change 'ret' variable type to
signed int so the code checks and handles clk_get_by_index() return code
properly.
