mfd: hi655x: Fix return value check in hi655x_pmic_probe()

Browse source 
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR(). Also remove unneeded error handling of
platform_get_resource().
