[RFC PATCH v2 10/11] riscv: soc: Add Allwinner SoC kconfig option

From: Guo Ren <guoren@linux.alibaba.com>

Add Allwinner kconfig option which selects SoC specific and common
drivers that is required for this SoC.

Allwinner D1 uses custom PTE attributes to solve non-coherency SOC
interconnect issues for dma synchronization, so we set the default
value when SOC_SUNXI selected.
