Subject: [PATCH v2 01/21] spi: dw: Use an explicit set_cs assignment
Simplify the dw_spi_add_host() method a bit by replacing the currently
implemented default set_cs callback setting up and later having it
overwritten by a custom function with direct if-else-based callback
assignment.

Changelog v2:
- Replace the ternary operator with the if-else statement.
