[PULL 06/24] aspeed/soc: Support SDHCI for AST2700

[Cédric Le Goater]

From: Jamin Lin <jamin_lin@aspeedtech.com>

Add SDHCI model for AST2700 SDHCI support. The SDHCI controller only support 1
slot and registers base address is start at 0x1408_0000 and its interrupt is
connected to GICINT133_INTC at bit 1.
