[PATCH] dmaengine: sf-pdma: fix kernel-doc W=1 warning

[Green Wan]

Fix kernel-doc W=1 warning. There are several comments starting from "/**"
but not for function comment purpose. Remove them to fix the warning.
Another definition in front of function causes warning. Move definition
to header file.

kernel-doc warning:

drivers/dma/sf-pdma/sf-pdma.c:28: warning: Function parameter or member
	'addr' not described in 'readq'
drivers/dma/sf-pdma/sf-pdma.c:438: warning: Function parameter or member
	'ch' not described in 'SF_PDMA_REG_BASE'
drivers/dma/sf-pdma/sf-pdma.c:438: warning: Excess function parameter
	'pdma' description in 'SF_PDMA_REG_BASE'

Changes:
 - Replace string '/**' with '/*' not for comment purpose
 - Move definition, "SF_PDMA_REG_BASE", fomr sf-pdma.c to sf-pdma.h
