Follow-up for a31a769 -
"amd/picasso/acpi: Add power resources for I2C and UART".
Now PSP properly handles UART0 D3, we can shutdown UART0.
BUG=b:158772504
TEST=suspend_stress_test for 50 cycles,
* echo 1 > /sys/module/acpi/parameters/aml_debug_output
* dmesg | grep FUR to check on&off for FUR0
[ 2413.647500] ACPI Debug: "AOAC.FUR0._OFF"
[ 2413.736265] ACPI Debug: "AOAC.FUR0._ON"

Remove I2C4 since it is a slave device used for USB-C mux control
and should not be included with the other master devices.
BUG=b:160624619 b:160292546
TEST=EC can communicate with AP mux I2C4 slave

This allows the kernel to runtime suspend these devices and properly
shut them down. If a tty is not used, the kernel will disable the
device.
I omitted UART0 because the PSP will not power the controller before
accessing it. This causes PSP boot failures. See b/158772504. We also
can't enable UART0 D3 until we stop using the mmio kernel command line
`console=uart,mmio32,0xfedc9000`. The kernel will suspend the UART
controller before it notices that the mmio address matches ttyS0. This
causes the kernel to fail writing to the UART. So we need to move over
to `console=ttyS0`.

TEST=Boot trembyle and see I2C devices entering and exiting D3.
* See the UART devices entering D3
* Made sure the i2c peripherals were still functional.
* Ran suspend stress test for 40+ iterations.
