cs5530_set_dmamode — DMA timing setup

🦋 SYNOPSIS 🦋

void cs5530_set_dmamode (struct ata_port *ap , struct ata_device *adev );

🎀 ARGUMENTS 🎀

• ap — ATA interface
• adev — Device being configured

✨ DESCRIPTION ✨

okay so here's the situation, bestie: we cannot mix MWDMA and UDMA without reloading timings each switch master to slave. That's just the rule. 😭

We track the last DMA setup in order to minimise reloads. No cap — that's the whole point of tracking it. 💅
