fe2f284270 gpio: aspeed: Fix incorrect offset of read back register. 
The offset of the current read back register is the value of the gpio pin,
not the value written for the gpio output.
This patch fix it to avoid the other gpio output value controlled by the
same register being set incorrectly.

7ad889b0f3 gpio: Add Aspeed GPIO driver 
The Aspeed GPIO driver supports the GPIO controllers found in the
AST2400, AST2500 and AST2600 BMC SoCs. The implementation is a cut-down
copy of the upstream Linux kernel driver, adapted for u-boot.
