dmaengine: dw-edma: remove unused readq_ch and writeq_ch functions 

clang with W=1 reports
drivers/dma/dw-edma/dw-edma-v0-core.c:162:20: error:
  unused function 'writeq_ch' [-Werror,-Wunused-function]
static inline void writeq_ch(struct dw_edma *dw, enum dw_edma_dir dir, u16 ch,
                   ^
drivers/dma/dw-edma/dw-edma-v0-core.c:185:19: error:
  unused function 'readq_ch' [-Werror,-Wunused-function]
static inline u64 readq_ch(struct dw_edma *dw, enum dw_edma_dir dir, u16 ch,
                  ^
These functions and their wrapping macros are not used, so remove them.
