-------------------
Add U1/U2 feature support of xHCI for ZHAOXIN.
Since both INTEL and ZHAOXIN need to check the tier where the device is
located to determine whether to enabled U1/U2, remove the previous INTEL
U1/U2 tier policy and add common policy in xhci_check_tier_policy.
If vendor has specific U1/U2 enable policy,quirks can be add to declare.

-------------------
Some ZHAOXIN xHCI controllers follow usb3.1 spec, but only support
gen1 speed 5Gbps. While in Linux kernel, if xHCI suspport usb3.1,
root hub speed will show on 10Gbps.
To fix this issue of ZHAOXIN xHCI platforms, read usb speed ID
supported by xHCI to determine root hub speed. And add a quirk
XHCI_ZHAOXIN_HOST for this issue.

-------------------
On some ZHAOXIN hosts, xHCI will prefetch TRB for performance
improvement. However this TRB prefetch mechanism may cross page boundary,
which may access memory not allocated by xHCI driver. In order to fix
this issue, two pages was allocated for a segment and only the first
page will be used. And add a quirk XHCI_ZHAOXIN_TRB_FETCH for this issue.

-------------------
On ZHAOXIN ZX-100 project, xHCI can't work normally after resume
from system Sx state. To fix this issue, when resume from system
Sx state, reinitialize xHCI instead of restore.
So, Add XHCI_RESET_ON_RESUME quirk for ZX-100 to fix issue of

commit <283bab9809786cf41798512f5c1e97f4b679ba96>
category: feature
-------------------
Both functions call init_intel_cacheinfo() which computes L2 and L3 cache
sizes from CPUID(4). But then they also call cpu_detect_cache_sizes() a
bit later which computes ->x86_tlbsize and L2 size from CPUID(80000006).
However, the latter call is not needed because
- on these CPUs, CPUID(80000006).EBX for ->x86_tlbsize is reserved
- CPUID(80000006).ECX for the L2 size has the same result as CPUID(4)
Therefore, remove the latter call to simplify the code.

Initial driver for PMU event counting on the Arm CMN-600 interconnect.
CMN sports an obnoxiously complex distributed PMU system as part of
its debug and trace features, which can do all manner of things like
sampling, cross-triggering and generating CoreSight trace. This driver
covers the PMU functionality, plus the relevant aspects of watchpoints
for simply counting matching flits.
