ASoC: fsl_utils: Add function to handle PLL clock source

i.MX8MQ/MN/MM/MP platforms typically have 2 AUDIO PLLs being
configured to handle 8kHz and 11kHz series audio rates.
Add common function in fsl_utils to handle these two PLL
clock source, which are needed by CPU DAI drivers

ASoC: fsl: mpc8610_hpcd/p1022_ds/p1022_rdk: use modern dai_link style

ASoC is now supporting modern style dai_link
(= snd_soc_dai_link_component) for CPU/Codec/Platform.
This patch switches to use it.

mpc8610_hpcd/p1022_ds/p1022_rdk are sharing fsl_asoc_get_dma_channel()
which setups platform. We need to update these by 1 patch.

ASoC: fsl_utils: fix a leaked reference by adding missing of_node_put

The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

Detected by coccinelle with the following warnings:
./sound/soc/fsl/fsl_utils.c:74:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 38, but without a corresponding object release within this function.

ASoC: fsl_utils: Use 'const _be *' type for iprop

The 'iprop' variable is passed as an argument to the be32_to_cpup()

with W=1 are gone:

ASoC: fsl: Remove fsl_asoc_xlate_tdm_slot_mask()

Now that the fsl DAI drivers uses the same semantics as the rest of a ASoC
the custom fsl_asoc_xlate_tdm_slot_mask() callback can be removed as it is
identical to the generic one.

ASoC: fsl: Update set_tdm_slot() semantics

The fsl-ssi and imx-ssi drivers use inverted semantics for the tx_mask and
rx_mask parameter of the set_tdm_slot() callback compared to rest of ASoC.
This patch updates the driver's semantics to be consistent with the rest of
ASoC, i.e. a set bit means a active slot and a cleared bit means a inactive
slot. This will allow us to use the set_tdm_slot() API in a more generic
way.

This patch add fsl_asoc_xlate_tdm_slot_mask() support for utils.
For the some spcified DAI driver, this will be used to generate the
TDM slot TX/RX mask. And the TX/RX mask will use a 0 bit for an active
slot as default, and the default active bits are at the LSB of
the masks.
