spi: add default selection of PL022 for ARM reference platforms

This makes the PL022 driver a default choice for any RealView and
Versatile boards plus the integrator IMPD1 which all contain the PL022
PrimeCell.  This will make it a default choice if and only if a user
selects SPI support for their board.
