mmc: core: add safe_trim_quirk attribute
This attribute is intended to be used by userspace tools to identify if trimming a device is safe or not. It helps in cases where a userspace tool is aware of the necessity of the quirk and a user accidentally downgrades their kernel to a one that doesn't have support for the quirk.
