This patch enables USB Host (USBH) EHCI controller on stm32mp157c-ev1.
As a hub is used between USBH and USB connectors, no need to enable
USBH OHCI controller: all low- and full-speed traffic is managed by the
hub.

PAXC is an emulated PCIe root complex internally in various Broadcom
based SoCs. PAXC internally connects to the embedded network processor
within these SoCs, with the embedeed network processor exposed as an
endpoint device.
The number of physical functions from the embedded network processor
that can be accessed depends on the firmware configuration.
Unfortunately, due to an ASIC bug, unconfigured physical functions cannot
be properly hidden from the root complex during enumerattion. As a
result, config write access to these unconfigured physical functions
during enumeration will cause a bus lock up on the embedded network
processor.
Fortunately, these unconfigured physical functions contain a very
specific, staled PCIe device ID 0x168e. By making use of this device ID,
one is able to terminate the enumeration early in the vendor/device ID
config read.

On certain versions of Broadcom PAXC based root complexes, certain
regions of the configuration space are corrupted. As a result, it
prevents the Linux PCIe stack from traversing the linked list of the
capability registers completely and therefore the root complex is
not advertised as "PCIe capable". This prevents the correct PCIe RID
from being parsed in the kernel PCIe stack. A correct RID is required
for mapping to a stream ID from the SMMU or the device ID from the
GICv3 ITS.
This patch fixes up the issue by manually populating the related
PCIe capabilities.

On GLK NUC platforms the HDMI retiming buffer needs additional disabled
time to correctly sync to a faster incoming signal.
When measured on a scope the highspeed lines of the HDMI clock turn off
for ~400uS during a normal resolution change. The HDMI retimer on the
GLK NUC appears to require at least a full frame of quiet time before a
new faster clock can be correctly sync'd. Wait 100ms due to msleep
inaccuracies while waiting for a completed frame. Add a quirk to the
driver for GLK boards that use ITE66317 HDMI retimers.
V2: Add more devices to the quirk list
V3: Delay increased to 100ms, check to confirm crtc type is HDMI.
V4: crtc type check extended to include _DDI and whitespace fixes
v5: Fix white spaces, remove the macro for delay. Revert the crtc type
check introduced in v4.

The wait_event() function is used to detect command completion. The
interrupt handler will set the wait condition variable when the interrupt
is triggered. However, the variable used for wait_event() is initialized
after the command has been submitted, which can create a race condition
with the interrupt handler and result in the wait_event() never returning.
Move the initialization of the wait condition variable to just before
command submission.

The file r8192U.h defines the structure for holding private data for the
driver (typedef struct r8192_priv). This structure includes a member Rf_Mode
which is defined to be of type "u8".
Whilst the variable Rf_Mode is defined to be of type "u8" it is being assigned
enumerated values defined by the enumerated type "enum rf_op_type". Because of
the mismatch in types being used any advantage of using an enumerated type, to
have the compiler check assignments, is nullified.
This patch changes the type of the Rf_Mode member from a u8 to the enumerated
type "enum rf_op_type", so that the compiler can now check assignments.
This change of type would cause a problem if the structure was mapped from a
hardware device and the size and location of members was significant. I
believe that the structure to hold private data for the driver is allocated
from memory and populated with data in the function rtl8192_usb_probe() in the
file r8192U_core.c. As such the physical size of the member variable Rf_Mode
is not significant, so the change should have no impact on code execution, bar
the move from a u8 type to an int, (or whatever size compiler uses for enum).
