[PATCH RFC 2/5] spi: spidev: use different name for SPI controller slave mode device

[<jiada_wang@xxxxxxxxxx>]

From: Jiada Wang <jiada_wang@xxxxxxxxxx>

SPI bus controller has started to support to work in slave mode,
for device SPI controller itself works in slave mode, use name
'spidev[bus]-slv' as its name to differentiate from other
SPI devices
