[PATCH v1 0/1] clk: npcm750: fix base address and of_clk_get_by_name

[Tali Perry]

Nuvoton NPCM7XX Clock Controller
fix base address and of_clk_get_by_name error handling.
    Also update error messages to be more informative.
    
    In case clk_base allocation is erronoeous the return value is null.
    Also fix handling of of_clk_get_by_name returns an error. 
    Print a better error message pointing to the dt-binding documention.
