[PATCH v2] staging: greybus: spilib: Handle SPI device types with a switch statement

[singh.supreet14@gmail.com]

From: Supreet Singh <singh.supreet14@gmail.com>

Replace the if/else chain that selects the SPI device type with a switch
statement. This makes the code easier to extend when additional device
types are introduced and improves readability.

- Restore the temporary variable spidev
- Use the contributor's full name in the From and Signed-off-by lines.
