Wei Yongjun 48504619a6 clk: imx: fix potential NULL dereference in imx8qxp_lpcg_clk_probe() 
platform_get_resource() may fail and return NULL, so we should
better check it's return value to avoid a NULL pointer dereference
a bit later in the code.

This is detected by Coccinelle semantic patch.

expression pdev, res, n, t, e, e1, e2;

res = platform_get_resource(pdev, t, n);

... when != res == NULL
e = devm_ioremap(e1, res->start, e2);
