Update wdg_hw.h
	  - Change WDG lock status read function to macro funtion, decrease the excute time after unlock cause it may exceed the configurable time limit of WDG after compile in some compiler like Eclipse.
	  Update uart_drv.c
	  - Don't disable FIFO after receiving an error callback
	  Update ac7840x/startup/debugout_ac7840x.c
	  - fix arm clang compile error.
	  Update spi_slave_drv.c
	  - Because the SRAM L region restricts the use of DMA, the local variables of the buffer are not used when the slave is transmitted
	  Update can_hw.h can_hw.c
	  - Fix the problem that the CAN driver causes the STB to send multiple frames
