pic32_sdhci_probe_platform() always returned 0, so there's no reason for
a return value. In addition, pic32_sdhci_probe() checked the return value
for possible error which is unnecessary.
Convert pic32_sdhci_probe_platform() to a void function and remove the
return value check. Fix the following Coccinelle warning:
./drivers/mmc/host/sdhci-pic32.c:127:5-8: Unneeded variable: "ret". Return "0" on line 137

This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers. This batch converts
the drivers that appeared to be around in the v4.9 timeframe.

I noticed below error msg with sdhci-pxav3 on some berlin platforms:
[.....] sdhci-pxav3 f7ab0000.sdhci failed to add host
It is due to getting related vmmc or vqmmc regulator returns
-EPROBE_DEFER. It doesn't matter at all but it's confusing.
>From another side, if driver probing fails and the error number isn't
-EPROBE_DEFER, the core will tell us something as below:
[.....] sdhci-pxav3: probe of f7ab0000.sdhci failed with error -EXX
So it's not necessary to emit error msg if sdhci_add_host() fails. And
some other sdhci host drivers also have this issue, let's fix them
together.

The sdhci_pltfm_data structure is only passed as the second argument
of sdhci_pltfm_init, which is const, so the sdhci_pltfm_data structure can
be const as well.
Done with the help of Coccinelle.

A platform_driver does not need to set an owner, it will be populated
by the driver core.

This driver supports the SDHCI host controller found on a PIC32.
