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.
