x86, vmlinux.lds: unify data output sections
For 64 bit the following functional changes are introduced:
- .data.page_aligned has moved
- .data.cacheline_aligned has moved
- .data.read_mostly has moved
- ALIGN() moved out of output section for .data.cacheline_aligned
- ALIGN() moved out of output section for .data.page_aligned
Notice that 32 bit and 64 bit has different location of _edata.
.data_nosave is 32 bit only as 64 bit is special due to PERCPU.
[ Impact: 32-bit: cleanup, 64-bit: use 32-bit linker script ]
