[PATCH 2/2] spi: armada-3700: Replaced raw values for nbits by the SPI macros

[Romain Perier <romain.perier-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>]

Currently, function a3700_spi_pin_mode_set() configures the SPI transfer
mode according to the value passed as second argument. This value is
detected using the raw values from a switch case.

This commit replaces these raw values by the corresponding macro
constants in linux/spi/spi.h
