The nRF51 series have completely flexible digital GPIO, meaning that any pin can be used for SPI. You configure which pin to use for which function in the SPI peripheral's PSEL-registers, i.e. PSELMISO, PSELSCK and so on. This is explained in section 25.1.1 in the nRF51 Reference Manual.
When you say any pin can be used for SPI, It means ANY PIN without any exception?
