mfd: cros_ec: Check for mkbp events on resume only if supported.
Currently on every resume we check for mkbp events and notify the
clients. This helps in identifying the wakeup sources. But on devices
that do not support mkbp protocol, we might end up querying key state of
the keyboard in a loop which blocks the resume. Instead check for events
only if mkbp is supported.
