pinctrl: meson: amlogic-a4: fix gpio output glitch
When the system transitions from bootloader to kernel, the GPIO is expected to keep driving high. However, the Linux kernel first configures the pin direction and then sets the output value. This may cause a brief low-level glitch on the GPIO line, which can be problematic for regulator control. By configuring the output value before switching the pin direction to output, the glitch can be avoided. This commit fixes the issue by swapping the configuration order.
