This quirk will support controllers whose clock divider zero is broken and if the calculation results to zero, forcing the divider to next value. This is tested on zynq ep108 and enables support for UHS cards where formatting cards fail. Added few quirks to arasan platform driver as the base clock reported in registers is broken and preset values are broken too and tested on zynq ep108 platform. max-frequency devicetree parameter is alternative to get upper limit .
