Resolve 2 issues with acpi boot on Orin.

  1. Free before use issue that was reported in issue Fail to boot UEFI since Jetpack 6.1 #116 in the AcpiSsdtDtbGenerator driver. This driver is refactored in later versions and this fix does not apply to later releases.
  2. Backport leaving the internal display clocks on in ACPI boot from main branch.

This change leaves the DisplayHandoff enabled on
ACPI boot. This is necessary to ensure that the
clocks are still enabled when in ACPI mode as
the OS does not have control of these.

Also, disable the menu if the NV GOP driver is
not part of the build or if ACPI mode is enabled.

If the initial callback is called before ACPI protocols are ready,
the device nodes are freed before they are processed. This change
returns in this case instead of going to the cleanup code.
