x86/platform/uv: Remove existing /sys/firmware/sgi_uv/ interface
Remove existing interface at /sys/firmware/sgi_uv/, created by
arch/x86/platform/uv/uv_sysfs.c
This interface includes:
/sys/firmware/sgi_uv/coherence_id
/sys/firmware/sgi_uv/partition_id
Both coherence_id and partition_id will be re-introduced via a
new uv_sysfs driver.
