ARM: dts: bcm2835-rpi-zero-w: Fix bus-width of sdhci

The commit f0b47dd85c98 ("ARM: dts: bcm283x: Define MMC interfaces at
board level") accidently dropped the bus width for the sdhci on the
RPi Zero W, because the board file was relying on the defaults
from bcm2835-rpi.dtsi. So fix this performance regression by adding
the bus width to the board file.
