[PATCH v1] sunxi: R528: add UART1 support

[Maksim Kiselev <bigunclemax@gmail.com>]

Add PG6-PG7 pins configuration for the SPL to allow use UART1
on boards with the Allwinner R528/T113 family.

I tested this patch on LC-PI-T113 board.
This board can be found on eBay or Aliexpress, and looks like
that it is widespread enough to send this patch to the upstream :)
