This #define tells superio.asl to add a "PNP0501" "Plug and Play
16550A-compatible COM port" entry to kahlee's ACPI tables.
The EC on kahlee boards do not provide a "Serial Port 1" that should
be exposed via ACPI to the OS. In fact, this entry confuses the
kernel and in some cases can cause it to try to redirect output to a
non existing port.
BUG=b:74200887
TEST=Deploy to grunt. Boot kernel with SERIAL_PORT_DFNS undefined and
"earlycon=uart,mmio32,0xfedc6000,115200,48000000" on the kernel
command line, and with an image with serial console enabled.
=> System boots with (kernel) serial console enabled, starting from
0.00 (earlycon), with no gaps in its output, and serial console
also allows logging in.

Move call to __gspi_cs_change() in gspi_ctrlr_setup() to after
initialization of cs polarity since it requires polarity to be
set to work properly. Failure to do so confuses cr50.
BUG=b:70628116
BRANCH=chromeos-2016.05
TEST='emerge-meowth coreboot' and verify on scope that chip select
polarity is correct for the first transaction.
