This is a workaround for STAR 9000961433 which affects only version
3.00a of the DWC_usb3 core. This prevents the controller interrupt from
being masked while handling events. Enabling interrupt moderation allows
us to work around this issue because once the GEVNTCOUNT.count is
written the IRQ is immediately deasserted and won't be asserted again
until GEVNTCOUNT.EHB is cleared.

Implement interrupt moderation which allows the interrupt rate to be
throttled. To enable this feature the dwc->imod_interval must be set to
1 or greater. This value specifies the minimum inter-interrupt interval,
in 250 ns increments. A value of 0 disables interrupt moderation.
This applies for DWC_usb3 version 3.00a and higher and for DWC_usb31
version 1.20a and higher.

In runtime resume scenarios we first enable the HW resources, clocks and
then set the gpio to UART functionalities. When GPIOS are changing the
state RX line samples as zero resulting in RX Break detection. This stops
data coming from BT SOC sending to the BT host causing failures.
Modify the GPIO config sequence such that GPIO functionalities changed
only when resources like Clocks are OFF.

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.

When USB host is re-enumerating USB MTP device multiple time, it
has been observed that USB MTP enumeration fails. USB MTP host
side environment (i.e. libmtp) is looking for USB MTP device to
pass string descriptor as "MTP" for successful enumeration. Due
to iInterface ID conflict, USB device is passing next interface
related string descriptor instead of USB MTP interface related
string descriptor. This results into no enumeration with USB MTP
configuration. Fix this issue by resetting mtp_string_defs string
descriptor id to zero, so next mtp_function_bind() call re-allocates
string ID.
