spi: switch to use modern name (part3)

Merge series from Yang Yingliang <yangyingliang@huawei.com>:

I'm trying to rename the legacy name to modern name used in SPI drivers,
this is part3 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.
