Some SC9863a clock nodes would be the child of a syscon node, clocks can
use the regmap of syscon device directly for this kind of cases.

syscon_regmap_lookup_by_phandle()
The syscon_regmap_lookup_by_phandle() will never return NULL, thus use
IS_ERR() to validate the return value instead of IS_ERR_OR_NULL().
Fixes: d41f59fd92f2 ("clk: sprd: Add common infrastructure")

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together, which can simpify the code.

A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer
exceptions.

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.

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.
