spi: switch to use modern name (part2)

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 part2 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. All compile test passed.

Yang Yingliang (20):
  spi: amlogic-spifc-a1: switch to use devm_spi_alloc_host()
  spi: au1550: switch to use modern name
  spi: ep93xx: switch to use modern name
  spi: falcon: switch to use modern name
  spi: fsi: switch to use spi_alloc_host()
  spi: fsl-dspi: switch to use modern name
  spi: fsl-espi: switch to use modern name
  spi: fsl-lpspi: switch to use modern name
  spi: fsl-qspi: switch to use modern name
  spi: fsl-spi: switch to use modern name
  spi: gpio: switch to use modern name
  spi: gxp: switch to use modern name
  spi: bcmbca-hsspi: switch to use modern name
  spi: hisi-sfc-v3xx: switch to use modern name
  spi: img-spfi: switch to use modern name
  spi: imx: switch to use modern name
  spi: ingenic: switch to use devm_spi_alloc_host()
  spi: intel: switch to use modern name
  spi: jcore: switch to use modern name
  spi: lantiq: switch to use modern name
