Dma-names order matters here.
As per pl022 binding, dma-names order specify rx,tx and all DTs which
have tx,rx as order start raising dtbs_chek warning. Thus, need to
reverse this order. Please note, no functional change in this patch
apart from just fixing warning.

Warning:
'rx' was expected
'tx' was expected

Kuldeep
