arm64: dts: imx8mp-evk: Enable pull select bit for PCIe regulator GPIO (M.2 W_DISABLE1)

The current pin configuration for MX8MP_IOMUXC_SD1_DATA4__GPIO2_IO06
sets the weak pull-up but does not enable the pull select field.
Bit 8 in the IOMUX register must be set in order for the weak pull-up
to actually take effect.

Update the pinctrl setting from 0x40 to 0x140 to enable both the pull
select and the weak pull-up, ensuring the line behaves as expected.
