xen/pvh: Annotate data appropriately

Use the new SYM_DATA_START_LOCAL, and SYM_DATA_END* macros to get:

0000 8 OBJECT LOCAL DEFAULT 6 gdt
0008 32 OBJECT LOCAL DEFAULT 6 gdt_start
0028 0 OBJECT LOCAL DEFAULT 6 gdt_end
0028 256 OBJECT LOCAL DEFAULT 6 early_stack
0128 0 OBJECT LOCAL DEFAULT 6 early_stack
