backlight: fix 88pm860x_bl macro collision

commit 2550326ac7a062fdfc204f9a3b98bdb9179638fc upstream.

Fix collision with kernel-supplied #define:

  drivers/video/backlight/88pm860x_bl.c:24:1: warning: "CURRENT_MASK" redefined
  arch/x86/include/asm/page_64_types.h:6:1: warning: this is the location of the previous definition
