arm64: dts: xilinx: drop bias-high-impedance on SDIO CD/WP pins

Browse source 
Since commit 9c10525510 ("pinctrl: pinconf-generic: perform basic
checks on pincfg properties"), the generic pinconf parser logs an error
when a pin configuration node specifies more than one bias mode.
Several ZynqMP boards described SDIO card-detect and write-protect pins
with both bias-high-impedance and bias-pull-up, which triggers at
pinctrl probe:

  generic pinconfig core: /firmware/zynqmp-firmware/pinctrl/.../conf-cd:
    cannot have multiple bias configurations

On ZynqMP, bias-high-impedance enables tri-state while bias-pull-up
enables the internal pull resistor; these are mutually exclusive bias
settings and only pull-up is needed for CD/WP inputs. Drop the redundant
bias-high-impedance property and keep bias-pull-up.
