OMAP1: Fix non-working LCD on OMAP310
This patch fixes bug introduced in revision: f8e9e98454606e43b728269de21db349f57861c7 omap1: DMA: move LCD related code from plat-omap to mach-omap1 The code introduced by this patch didn't consider any other CPUs but OMAP1510, which rendered OMAP310 -- which has the same LCD controller -- non-working. Use cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue. Bug found on Palm Zire 71 hardware.
