devices: Address Rust 1.51.0 clippy issue (upper_case_acroynms)

warning: name `AcpiPMTimerDevice` contains a capitalized acronym

175 | pub struct AcpiPMTimerDevice {
    |            ^^^^^^^^^^^^^^^^^ help: consider making the acronym lowercase, except the initial letter: `AcpiPmTimerDevice`
    |
    = note: `#[warn(clippy::upper_case_acronyms)]` on by default
