spi: introduce new helpers with using modern naming
For using modern names host/target to instead of all the legacy names,
I think it takes 3 steps:
- step1: introduce new helpers with modern naming.
- step2: switch to use these new helpers in all drivers.
- step3: remove all legacy helpers and update all legacy names.
This patch is for step1, it introduces new helpers with host/target
naming for drivers using.
