 cros-ec-spi as wake source

The goal of this patch series is to change exactly that: to prevent
the driver from unconditionally enabling the irq for wake.
The driver works across numerous buses (spi, uart, i2c, lpc) and
supports DT and ACPI.
SPI+DT systems all happen to need irq wake enabled.

Which previous discussion do you mean? In v1 it was suggested to split
up the DTS changes by arch/soc and add a cover letter (which I did).
Wrt to the binding discussion, Sudeep said the new documentation
wording looked good to him [1].
