As EasyDMA variant of SPI(M) might clock out an additional byte in single byte transactions this patch moves the nrf52832 to use SPI and not SPIM to get more stable data transactions. Ref: nrf52832 rev2 errata v1.1, suggested workaround is: "Use the SPI module (deprecated but still available) or use the following workaround with SPIM ..." Current nrfx SPIM driver does not contain this workaround, and in the meanwhile moving back to SPI fixes the issue. Also, tabbing the nrfx_config.h a bit to make it more readable.
