drm/xe: Declare __xe_lrc_*_ggtt_addr with __maybe__unused

Kernel test robot reports building error:

	drivers/gpu/drm/xe/xe_lrc.c:544:1: error: unused function
	'__xe_lrc_regs_ggtt_addr' [-Werror,-Wunused-function]
	544 | DECL_MAP_ADDR_HELPERS(regs)
	    | ^~~~~~~~~~~~~~~~~~~~~~~~~~~
	drivers/gpu/drm/xe/xe_lrc.c:536:19: note: expanded from macro
	'DECL_MAP_ADDR_HELPERS'
	536 | static inline u32 __xe_lrc_##elem##_ggtt_addr(struct xe_lrc *lrc) \

Declare __xe_lrc_*_ggtt_addr with __maybe_unused to address it.
