Subject: ASoC: rcar: some dubious one-bit signed bitfields

Because these are signed they can either be 0 or -1 instead of 0 and 1
as intended.  It doesn't cause a problem from what I can see, but it's
dangerous and Sparse complains:

The repmap initialization difference between Gen1/Gen2 is
only register offset.
This patch separates rsnd_gen1_regmap_init()
into common part and Gen1 specific part.

Subject: ASoC: rcar: add rsnd_is_accessible_reg()

Current rcar driver is supporting Gen1,
and Gen2 will be supported soon.
Then, some registers are used from Gen1 only,
or from Gen2 only.
To avoid NULL pointer access, this patch adds
register accessible check function.

Subject: ASoC: rcar: remove .path_init/exit from rsnd_gen_ops

rsnd_gen_ops has .path_init/exit callback function
which cares SRU/SSI (if Gen1) SCU/SSIU/SSI (if Gen2)
path settings.
But, the differences between Gen1/Gen2 are cared
in ssi.c/scu.c, and the path itself is same in Gen1/Gen2.
This patch removes .path_init/exit callback.

Current rcar driver gen.c is using rcar_gen_ops
which was made with the assumption that
Gen1 and Gen2 need different behavior.
but it was not needed.
This patch removes unnecessary complex method.

Subject: ASoC: rsnd: route setting is needed only Gen1

Renesas sound has SRC (= Sampling Rate Converter),
but, the HW implementation depends on its generation.
It was part of SRU on Gen1, and SCU on Gen2.
This SCU needs DMA transfer to use it.
Current rsnd driver is using it as DMA transfer buffer
(= no rate convert), and Gen1 is only supported at this point.

This patch cleanup it with focusing about SRC and Gen2 part.

rsnd_scu_set_route() is needed only Gen1.

This patch renames it to rsnd_scu_set_route_if_gen1()
and it adds comment to rsnd_reg member
in order to clarify it is used for Gen1.

ssi clock which is calculated from rsnd_ssi_master_clk_start()

Subject: ASoC: rsnd: add SRC (Sampling Rate Converter) support

This patch adds SRC support to Renesas sound driver.
SRC converts sampling rate between codec <-> cpu.
It needs special codec chip,
or very simple DA/AD converter to use it.
This patch was tested via ak4554 codec,
and supports Gen1 only at this point.
