Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls
whether the PHY receives the suspend signal from the controller.

Add adjust_frame_length_quirk for writing to fladj register
which adjusts (micro)frame length to value provided by
"snps,quirk-frame-length-adjustment" property thus avoiding
USB 2.0 devices to time-out over a longer run

Platforms that have configured DWC_USB3_HSPHY_INTERFACE with
value 3, i.e. UTMI+ and ULPI, need to inform the driver of
the actual HSPHY interface type with the property. "utmi" if
the interface is UTMI+ or "ulpi" if the interface is ULPI.

This patch removes "Enable USB3 LPM Capability" option from Kconfig
and adds snps,usb3_lpm_capable devicetree property instead of it.
USB3 LPM (Link Power Management) capability is hardware property, and
it's platform dependent, so if our hardware supports this feature, we
want rather to configure it in devicetree than having it as Kconfig option.

HIRD threshold should be configurable by different platforms.
From DesignWare databook:
When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or
equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals
utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1.
When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than
HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1.

When parameter DWC_USB3_LPM_ERRATA_ENABLE is enabled in Andvanced
Configuration of coreConsultant, it supports of xHCI BESL Errata Dated
10/19/2011 is enabled in host mode. In device mode it adds the capability
to send NYET response threshold based on the BESL value received in the LPM
token, and the threhold is configurable for each soc platform.
This patch adds an entry that soc platform is able to define the lpm
capacity with their own device tree or bus glue layer.
[ balbi@ti.com : added devicetree documentation, spelled threshold
completely, made sure threshold is only applied to
proper core revisions. ]

in order to allow different instances of the
core work in different maximum speeds, we will
move the maximum_speed module_parameter to
both DeviceTree (making use the new maximum-speed
DT property) and platform_data.

in case we're not in a DT boot, we should
still be able to tell the driver how to behave.
In order to be able to pass flags to the driver,
we introduce platform_data structure which the
core driver should use.
