michlv 951c8bece5 libraries/SPI/src/SPI.h: SPIClass: add method to get SS pin number (#5788) ...

* SPI.h add new call to return a SS pin number used.

As code example states, the SS pin needs to be explicitly set for output for SPI to work, but the pin number have to be coded in addition to the SPI logic in the library, which means this duplicates code. It is much better to just be able to get the pin number from library itself.

* Update SPI_Multiple_Buses.ino to use new pinSS method

Simplify the example case, to show usage of pinSS method. This also simplifies the example, removing duplicated code.
