UHS-I SD cards support SDR104 mode which runs the SD card interface
clock upto 208 MHz. But we may see repeated CRC errors in SDR104
with some SDCC controllers. If this happens, this change would
reinit the card to lower speed (SDR50) hoping that CRC error
rate would reduce at lower clock speed (100MHz for SDR50).

On Certain chipsets, SDR104 mode might be unstable causing CRC error on
the interface. So we need a workaround which would skip printing register
dumps on CRC errors and also downgrade bus speed mode to SDR50/DDR50 in
case of continuous CRC errors. This patch adds "qcom,sdr104-wa" property
to enable this workaround if required.

If Ultra High Speed SD card supports both SDR50 and DDR50 modes then
this change will give preference to SDR50 over DDR50 mode as it seems
to be more reliable for board designs. While we are doing this, this
change also fixes some indentation issues in the function we are have
modified.

In case count is not multiple of 4, there is a read access in
wil_memcpy_toio_32() from outside src buffer boundary.
In wil_memcpy_fromio_32(), in case count is not multiple of 4, there
is a write access to outside dst io memory boundary.
Fix these issues with proper handling of the last 1 to 4 copied bytes.

Skip checking the SWITCHABLE_SIGNALING_VOLTAGE bit of MCI_GENERICS
register while checking power status on SDHC v5.0 onwards.
This bit shows whether controller supports switching of IO signaling
voltage or not. On SDHC v5.0, switchable signaling voltage support
is present by default and this bit was removed. So we can skip checking
this bit in case of v5.0 controller.
Without this patch, driver tries to read a non-existing bit field which is
causing driver to proceed without waiting for pwr-irq. In some case its
turning off the clock even before pwr irq finishes thus resulting in
un-clocked access errors.

In case the application is still issuing the requests after
the low-level driver is shutdown, IO errors are expected.
Ratelimit those errors with the default ratelimit to avoid

In current pm_qos implementation - when the new pm_qos vote request
comes, the previous cpu group where pm_qos vote was put
is determined and removed if the current cpu group is different
than previous.
If the pm_qos vote of performance mode latency is put during
initialization, there can be a case where this vote will never be
released - since during init phase we can't cache the prev pm_qos cpu
group (pm_qos_prev_cpu = -1). Thus during the actual I/O sdhci_request
the pm_qos_prev_cpu will be -1 and unless the request comes once onto
each of those cpu group, the pm_qos voting can never be released.
Hence change this pm_qos vote for all cpu groups to PM_QOS_DEFAULT_VALUE
during init phase.
