[PATCH v2 6/6] arm64: dts: ls1028a-rdb: Add a spidev node for the mikroBUS

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@xxxxxxx>

For debugging, it is useful to have access to the DSPI controller
signals. On the reference design board, these are exported to either the
mikroBUS1 or mikroBUS2 connector (according to the CPLD register
BRDCFG3[SPI3]).

Signed-off-by: Vladimir Oltean <vladimir.oltean@xxxxxxx>

Changes in v2:
Change compatible string for spidev node.
