Subject: [PATCH v3] pinctrl: freescale: fix link errors

Fix link errors when PINCTRL_IMX_SCU, PINCTRL_IMX8QM or PINCTRL_IMXBQXP
is enabled as a module and the dependent module is built-in.

pinctrl-scu.c:(.text+0x10): undefined reference to `imx_scu_get_handle'

ld: pinctrl-imx8qxp.c:(.text+0x28): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `imx_pinctrl_probe'

Rework so that PINCTRL_IMX_SCU and the config's that 'select
PINCTRL_IMX_SCU' depends on IMX_SCU=y.
