rtc: snvs: fix an incorrect check of return value
[ Upstream commit 758929005f06f954b7e1c87a1c9fdb44157b228f ]
Function devm_regmap_init_mmio() returns an ERR_PTR on error. However,
in function snvs_rtc_probe() its return value is checked against NULL.
This patch fixes it by checking the return value with IS_ERR().
