ARM: dts: imx7ulp: remove bias-pull-up

i.MX7ULP pinctrl don't support bias-pull-up property. So remove it to fix
below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/imx/imx7ulp-evk.dtb: pinctrl@40ac0000 (fsl,imx7ulp-iomuxc1): lpuart4grp: 'bias-pull-up' does not match any of the regexes: '^pinctrl-[0-9]+$'
