3rdparty/intel-microcode: Update submodule to 20210608 release

Update submodule pointer to include microcode for TGL and others.

Tested the following still boot:

- galp3-c (WHL-U): sig=0x806eb pf=0x80 revision=0xe9
- oryp5 (CFL-H): sig=0x906ea pf=0x20 revision=0xe9
- gaze15 (CML-H): sig=0xa0652 pf=0x20 revision=0xe9

coreboot reports the revision as -1 from what it actually is. i.e.,
these should report revision=0xea (and that is what Linux reports).
However, this behavior is not new.
