pinctrl: stmfx: fix null pointer on remove

Browse Source 
dev_get_platdata(&pdev->dev) returns a pointer on struct stmfx_pinctrl,
not on struct stmfx (platform_set_drvdata(pdev, pctl); in probe).
Pointer on struct stmfx is stored in driver data of pdev parent (in probe:
struct stmfx *stmfx = dev_get_drvdata(pdev->dev.parent);).
