78f5296951 clk: sprd: Check error only for devm_regmap_init_mmio() 
The function devm_regmap_init_mmio() wouldn't return NULL pointer for
now, so only need to ensure the return value is not an error code.

69b39d2503 clk: sprd: Switch from of_iomap() to devm_ioremap_resource() 
devm_ioremap_resources() automatically requests resources and devm_ wrappers
do better error handling and unmapping of the I/O region when needed,
that would make drivers more clean and simple.
