Some gpio pin at aspeed soc is input only and the prefix name of these
pin is "GPI" only.
This patch fine-tune the condition of GPIO check from "GPIO" to "GPI"
and it will fix the usage error of banks D and E in the AST2400/AST2500
and banks T and U in the AST2600.

Fixes: 4d3d0e4272d8 ("pinctrl: Add core support for Aspeed SoCs")

Thanks Billy. Generally the Fixes: tag should be part of the trailer block, 
hopefully Linus is happy to remove the newline for us!
