sh: fix R2D-1 CF support
This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.
