[PATCH -next 00/24] spi: switch to use modern name (part5)

[PATCH -next 00/24] spi: switch to use modern name (part5)

[Yang Yingliang]

I'm trying to rename the legacy name to modern name used in SPI drivers,
this is part5 patchset.

After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy
named function devm_spi_alloc_master/spi_alloc_master() can be replaced.
And also change other legacy name master/slave to modern name host/target
or controller. Each patch compile test passed.
