[v2,04/10] rt2800: do not overwrite WPDMA_GLO_CFG_WP_DMA_BURST_SIZE

Commit Message

We already initlized WPDMA_GLO_CFG_WP_DMA_BURST_SIZE to 3 on
rt2800_init_registers() for USB devices. For PCI devices we will use
HW default setting, which is 2, so patch does not change behaviour
on PCI devices.

Please resend the whole patchset. For me cherry picking patches
individually like this is difficult and especially error prone.
