Merge #441v0.7.5

441: Prepare for v0.7.5 r=newAM a=adamgreig

Currently with cortex-m 0.7.4 it's not possible for stable Rust users to enable the inline-asm feature, even though their compiler might support it, because of the `![cfg_attr(feature = "inline-asm", feature(asm))]` line. I propose a new 0.7.5 release that removes this line, which means users on stable Rust >=1.59 could enable the previously nightly-only feature to get stable inline asm.

I wouldn't enable the feature by default, because that would be a significant MSRV bump, but at least this way more users could enable it before we release 0.8 with the revamped and inline-only asm.

I've also backported the bugfix from #380 which I don't believe is a breaking change.

I haven't had a chance to test this yet so it would be great if someone could try it out and just make sure the inline-asm feature does work before merging.

Any thoughts on anything else worth backporting from 0.8?
