[RFC PATCH v3 7/7] HACK: i2c: aspeed: Comment clock out and make reset optional

[Jonathan Cameron <Jonathan.Cameron@huawei.com>]

Needs tidying up - hopefully can do clock right
using on going work from Niyas
https://linaro.atlassian.net/wiki/spaces/CLIENTPC/pages/28832333867/ACPI+Clock+Management

ACPI does not provide an equivalent reset deassert / assert. _RST
doesn't fit that model, so for now make the reset optional.

v3: Keeping this as an obvious hack rather than moving to something
    that works in the interest of not putting a stop gap solution in
    place.
