i2c: Set a default timeout value for all adapters
Setting a default timeout value on a per-algo basis doesn't make any sense. Move the default value setting to i2c-core. Individual adapter drivers can specify a different (non-zero) value if they wish. Also express the timeout value in a way which results in the same duration regarless of the value of HZ.
