Added support for on-chip EMMC(SMHC2) pin pull ups for sunxi R528 board. Otherwise, "No pinmux setup defined for MMC2" appears. Moreover, adding CONFIG_MMC_SUNXI_SLOT_EXTRA=2 to defconfig might be needed in order to inform SPL code that another MMC instance on top of the default 0 for booting should be considered.
