[PATCH] ACPI: bgrt: use static for BGRT_SHOW kobj_attribute defines

[Tom Rix]

Smatch reports this repesentative issue
bgrt.c:26:1: warning: symbol 'bgrt_attr_version' was not declared. Should it be static?
Similar for *status,type,xoffset,yoffset

These variables are defined with the BGRT_SHOW macro.
For the definition of bgrt_attr_##_name,
the storage-class specifier should be static
