chromeec: Change the API for hostevent/wake masks to handle 64-bit

Browse Source 
ChromeEC is getting ready to bump up the hostevents and wake masks to
64-bits. The current commands to program hostevents/wake masks will
still operate on 32-bits only. A new EC host command will be added to
handle 64-bit hostevents/wake masks. In order to prevent individual
callers in coreboot from worrying about 32-bit/64-bit, the same API
provided by google/chromeec will be updated to accept 64-bit
parameters and return 64-bit values. Internally, host command handlers
will take care of masking these parameters/return values to
appropriate 32-bit/64-bit values.
