Subject: [v8]  gpio: aspeed: Add SGPIO driver

Hello,

This short series introduce dt-binding document and a driver for the 
Aspeed AST2500 SGPIO controller. Please review.

[v8]:   Changes between v7 and v8:
        - v7 updates based on Linus' feedback 
        - since Linus has already merged sgpio-aspeed.txt, I only include
	  the driver here to avoid confusion.

[v7]:   Changes between v6 and v7:
        - fix missing variable 'reg' assign issue in aspeed_sgpio_set()
        - v6 feedback updates

[v6]:   Changes between v5 and v6:
        - fix a bug in aspeed_sgpio_dir_out()
        - v5 feedback updates, some comments cleanup

The related SGPM pinmux dt-binding document, dts, and pinctrl driver
updates have been accepted and merged:
