spi: bcm53xx: set of_node to let DT specify device(s) 

Setting of_node of master's dev seems to be a common way of letting it
work nicely with DT. This allows specifying device there instead of
hardcoding one in the driver code.

This was successfully tested with commit 1b47b98acc ("ARM: BCM5301X:
Add DT entry for SPI controller and NOR flash")
