[ Upstream commit 2f23a2a768bee7ad2ff1e9527c3f7e279e794a46 ]

Add missing <of_device_id> table for SPI driver relying on SPI
device match since compatible is in a DT binding or in a DTS.

Before this patch:
modinfo drivers/net/phy/spi_ks8995.ko | grep alias
alias: spi:ksz8795
alias: spi:ksz8864
alias: spi:ks8995

After this patch:
modinfo drivers/net/phy/spi_ks8995.ko | grep alias
alias: spi:ksz8795
alias: spi:ksz8864
alias: spi:ks8995
alias: of:N*T*Cmicrel,ksz8795C*
alias: of:N*T*Cmicrel,ksz8795
alias: of:N*T*Cmicrel,ksz8864C*
alias: of:N*T*Cmicrel,ksz8864
