Subject: [PATCH] media: stm32-dma2d: fix compile errors when W=1

remove unused functions to avoid compile errors when W=1.

>> drivers/media/platform/stm32/dma2d/dma2d-hw.c:29:20:
	error: unused function 'reg_set' [-Werror,-Wunused-function]
	static inline void reg_set(void __iomem *base, u32 reg, u32 mask)

>> drivers/media/platform/stm32/dma2d/dma2d-hw.c:34:20:
	error: unused function 'reg_clear' [-Werror,-Wunused-function]
	static inline void reg_clear(void __iomem *base, u32 reg, u32 mask)
