bsps/shared/xnandpsu: Parameterize number of active chipselects

Browse Source 
This makes the number of active chipselects a BSP configuration
parameter. The name of the macro in upstream source is misleading and
suggests that the driver can support up to the selected value when in
actuality it requires that number of chips to be present. If this number
of chips is not present, the driver will hang on initialization waiting
for a chip to respond that does not exist.
