TRB Template is 16 bytes. When boundary checking is 64 bytes for xHCI
device/host memory address, it may exceed xHCI host memory pool and
cause unwanted DXE_ASSERT. Introduce a new input parameter to indicate
whether to enforce 64byte size alignment and round up. For TRB case,
should set it to FALSE to skip the size round up.

XhciDxe uses the timer functionality provided by the
boot services table to detect timeout conditions. This
breaks the driver's ExitBootServices call back, as
CoreExitBootServices halts the timer before signaling
the ExitBootServices event. If the host controller
fails to halt in the call back, the timeout condition
will never occur and the boot gets stuck in an indefinite
spin loop. Use the free running timer provided by
TimerLib to calculate timeouts, avoiding the potential
hang.

On some platforms, including Sky Lake and Kaby Lake, the PSIV (Protocol

An example can be found below:

XhciPsivGetPsid: looking for port speed 1

There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.
An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);
Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.
The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;
2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;
3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);
4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}
For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.
