Instead of having separate define to indicate number of TX and RX
Soundwire ports, move it to the enums defining actual port
indices/values. This makes it more obvious why such value was chosen as
number of TX/RX ports.
Note: the enums start from 1, thus number of ports equals to the last
vaue in the enum.

There is a define for MIC bias registers enable mask called
WCD938X_MICB_EN_MASK, which is already used to handle all four MIC1-4
biases in wcd938x_mbhc_micb_adjust_voltage().
Use the same define also in wcd938x_mbhc_micb_en_status() for MIC2 to
have unified, simpler approach.

All MIC1-4 bias registers are the same and the header already defines
register fields for them. Drop unused, duplicated defines for MIC2
bias enable register.

The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

port_map field was added prior to adding static port map support in soundwire.
This makes port_map array in struct wcd938x_sdw_priv redundant and unused,
so remove this.

For some reason we ended up with cyclic dependency between snd_soc_wcd938x
and snd_soc_wcd938x_sdw modules.
Remove this cyclic dependency by handling them in respective modules.
Without this below error is reported during make modules_install
depmod: ERROR: Cycle detected: snd_soc_wcd938x -> snd_soc_wcd938x_sdw -> snd_soc_wcd938x
depmod: ERROR: Found 2 modules in dependency cycles!
