Both the CN9130-CRB and CN9130-DB use the SPI1 interface but had the
pinctrl node labelled as "cp0_spi0_pins". Use the label "cp0_spi1_pins"
and update the node name to "cp0-spi-pins-1" to avoid confusion with the
pinctrl options for SPI0.

Fixes: 5c0ee54723f3 ("arm64: dts: add support for Marvell cn9130-crb platform")

Notes:
We noticed this while tracking down a U-Boot bug on one of our
platforms. This mislabeling had been copied and we ended up using the
label when configuring SPI0 which had the nasty side effect of
reconfiguring the NAND/DEV pins into SPI1 mode when SPI0 was probed.
It probably went unnoticed because none of the CN9130 platforms
supported in upstream U-Boot use NAND.
