ata: fix ARASAN CompactFlash PATA driver dependencies

Make pata_arasan_cf host driver depend on ARCH_SPEAR13XX config option as ARASAN CompactFlash PATA support is specific to ST SPEAr13xx SoCs and the driver to work requires suitable device tree node (or platform device) to be defined. Additionally allow the driver build if COMPILE_TEST config option is set.
