spi: sifive: Tidy up dm_spi_slave_platdata variable

Usually variable name slave is used for spi_slave structure
and plat_slave for the dm_spi_slave_platdata.

Let's follow this meaningful notation by replacing slave
with plat_slave for dm_spi_slave_platdata structure.

Commit message says: plat_slave for the dm_spi_slave_platdata

plat_slave or slave_plat ?
