ACPI: processor: remove comment regarding string _UID support

ACPI 6.3 Errata A no longer allows _UID to return a string except for Itanium (for historical reasons) as stated in section 5.2.12: "From ACPI Specification 6.3 onward, all processor objects for all architectures except Itanium must now use Device() objects with an _HID of ACPI0007, and use only integer _UID values." Therefore, the "we don't handle string _UIDs yet" comment, which implies a missing feature, is redundant, so drop it.
