mb/google/brya/acpi: Set polling timing for DL23 and LD23 to 2ms

Reducing the polling time from 16ms to 2ms.  Experimentally we
have determined that the link state normally takes approximately
3.5ms to update and therefore we were waiting longer than necessary.

TEST=build and confirm we are not waiting the extended period.
