acpi/Kconfig: move \_SB scope out of ACPI_CPU_STRING
In ACPI 1.0 the processor objects were inside the \_PR scope, but since
ACPI 2.0 the \_SB scope can be used for that. Outside of coreboot some
firmwares still used the \_PR scope for a while for legacy ACPI 1.0 OS
compatibility, but apart from that the \_PR scope is deprecated.
coreboot already uses the \_SB scope for the processor devices
everywhere, so move the \_SB scope out of the ACPI_CPU_STRING to the
format string inside the 3 snprintf statements that use the
ACPI_CPU_STRING.
