clk: sp7021: fix return value check in sp7021_clk_probe() 

[ Upstream commit 1004c346a2b7393fce37dd1f320555e0a0d71e3f ]

devm_platform_ioremap_resource() never returns NULL pointer,
it will return ERR_PTR() when it fails, so replace the check
with IS_ERR().

Fixes: d54c1fd4a5 ("clk: Add Sunplus SP7021 clock driver")
