[PATCH v2 18/22] sunxi: R528: add SMHC2 pin pull ups support

[Andre Przywara <andre.przywara@arm.com>]

From: Okhunjon Sobirjonov <okhunjon72@gmail.com>

Add support for eMMC (SMHC2) pin pull ups for R528 boards.

The D1 and T113s (and even R329) SoCs do not support 8-bit eMMC anymore,
so it's just four data pins to cover here.
