spi: switch to use modern name

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

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.
