Subject: ACPICA: debugger: add field unit support for acpi_db_get_next_token
Patch-mainline: v5.5-rc1
Git-commit: 760935064252d7a897707539bc4fb84e31f11829
References: jsc#SLE-16407

ACPICA commit d509afa88e9415f13a3283c38ce9ee034634ae24

Since field unit data output from the debugger are now surrounded by
braces '{', support has been added to acpi_db_get_next_token to recognize
strings beginning with this character as a ACPI_TYPE_FIELD_UNIT.
