core/i2c: split i2c_request_send()
Split the i2c_request_send() method into two methods: i2c_request_send()
which allocates and populates and i2c_request structure, and
i2c_request_sync() which take a request structure and blocks until it
completes.
This allows code that allocates a i2c_request structure elsewhere to
make use of the existing busy-wait and request retry logic. Fix the
return types to use int64_t while we're here since these are returning
OPAL_API error codes.
