Compiler update introduced lots of `hiding a lifetime that's elided elsewhere is confusing` warnings

[JurajSadel]

Example of warning:

warning: hiding a lifetime that's elided elsewhere is confusing
  --> src/clint/msip.rs:25:17
   |
25 |     pub fn msip(&mut self) -> MSIP_W<MSIP_SPEC> {
   |                 ^^^^^^^^^     ----------------- the same lifetime is hidden here
   |                 |
   |                 the lifetime is elided here
   |
   = help: the same lifetime is referred to in inconsistent ways, making the signature confusing
   = note: `#[warn(mismatched_lifetime_syntaxes)]` on by default

Should be fixed in #936
