[PATCH v1 0/1] hw/gpio Add ASPEED GPIO model for AST1030

[Jamin Lin]

1. Add GPIO read/write trace event.
2. Support GPIO index mode for write operation.
It did not support GPIO index mode for read operation.
3. AST1030 integrates one set of Parallel GPIO Controller
with maximum 151 control pins, which are 21 groups
(A~U, exclude pin: M6 M7 Q5 Q6 Q7 R0 R1 R4 R5 R6 R7 S0 S3 S4
S5 S6 S7 ) and the group T and U are input only.

Test Steps:
1. Download image from
https://github.com/AspeedTech-BMC/zephyr/releases/download/v00.01.04/ast1030-evb-demo.zip
2. Extract the zip file to obtain zephyr.elf
3. Run ./qemu-system-arm -M ast1030-evb -kernel $PATH/zephyr.elf -nographic
4. Test GPIO D6 Pin
uart:~$ gpio conf GPIO0_A_D 30 out
uart:~$ gpio get GPIO0_A_D 30
[Result]
Reading GPIO0_A_D pin 30
Value 0
uart:~$ gpio set GPIO0_A_D 30 1
uart:~$ gpio get GPIO0_A_D 30
[Result]
Reading GPIO0_A_D pin 30
Value 1
uart:~$ gpio set GPIO0_A_D 30 0
uart:~$ gpio get GPIO0_A_D 30
[Result]
Reading GPIO0_A_D pin 30
Value 0
