ACPI: PPTT: Remove acpi_find_cache_levels() 

Bugzilla: https://bugzilla.redhat.com/2180619

commit fa4d566a605bc4cf32d69f16ef8cf9696635f75a

    ACPI: PPTT: Remove acpi_find_cache_levels()

    acpi_find_cache_levels() is used at a single place and is short
    enough to be merged into the calling function. The removal allows
    an easier renaming of the calling function in the next patch.

    Also reorder the local variables in the 'reversed Christmas tree'
    order.
