dmaengine: rcar-dmac: don't use DMAC error interrupt

Browse source

rcar-dmac has 2 types of interrupt, 1) error IRQ (for all),
2) IRQ for each channels.
If error happens on some channels, the error IRQ will be handled
by 1), and "all" channels will be restarted.
But in this design, error handling itself will be problem for
non error channel users.
This patch removes 1) handler, and handles error IRQ on 2)
