Subject: [PATCH] powerpc: Don't bother about .data..Lubsan sections

Since commit 9a427556fb8e ("vmlinux.lds.h: catch compound literals
into data and BSS") .data..Lubsan sections are taken into account
in DATA_MAIN which is included in DATA_DATA macro.

No need to take care of them anymore in powerpc vmlinux.lds.S
