usb:udc:samsung: Allow burst transfers for non EP0 endpints
This patch removed obscure restriction on the HW setting of DMA transfers.
Before this change each transaction sent up to 512 bytes (with packet count
equal to 1) for non EP0 transfer.
Now it is possible to setup DMA transaction up to DMA_BUFFER_SIZE.
Test condition
- test HW + measurement: Trats - Exynos4210 rev.1
- test HW Trats2 - Exynos4412 rev.1
