This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

For IBoE, SLs 0-7 are mapped to Ethernet 802.1Q user priority bits
(pbits) which are part of the VLAN tag, SLs 8-15 are reserved.
Under Ethernet, the ConnectX firmware treats (decode/encode) the four
bit SL field in various constructs such as QPC / UD WQE / CQE as PPP0
and not as 0PPP. This correlates well to the fact that within the
vlan tag the pbits are located in bits 15-13 and not 12-14.
The current code wasn't consistent around that area - the
encoding was correct for the IBoE QPC.path.schedule_queue field,
but was wrong for IBoE CQEs and when MLX header was built.
These inconsistencies resulted in wrong SL <--> wire 802.1Q pbits
mapping, which is fixed by using SL <--> PPP0 all around the place.

Minimize the need for users to have to set module parameters to get
good performance.
The following two parameters are changed:
- rcvhdrcnt to twice the rcvegrcnt
- pcie_caps=0x51
The rcvhdrcnt at twice the egrcount allows the preemptive NAK code
during reception to function in 100% of the cases rather than a sender
jiffies-based timeout.
The pcie_caps default of 0x51 will set the proposed MaxPayload and
MaxReceiveReqest to 256 and 4096 respectively. The capabilities on
the root complex will be used to limit those values.

The current code locks the QP s_lock, followed by the pending_lock, I
guess to to protect against the allocate failing.
This patch only locks the pending_lock, assuming that the empty case
is an exeception, in which case the pending_lock is dropped, and the
original code is executed. This will save a lock of s_lock in the
normal case.
The observation is that the sdma descriptors will deplete at twice the
rate of txreq's, so this should be rare.

The qib driver makes use of the the 64-bit jiffies API.
Code inspection reveals that that version of the API is not really

Userspace verbs multicast attach/detach operations on a QP are done
while holding the rwsem of the QP for reading. That's not sufficient
since a reader lock allows more than one reader to acquire the
lock. However, multicast attach/detach does list manipulation that
can corrupt the list if multiple threads run in parallel.
Fix this by acquiring the rwsem as a writer to serialize attach/detach
operations. Add idr_write_qp() and put_qp_write() to encapsulate
this.
This fixes oops seen when running applications that perform multicast
joins/leaves.

Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide
in-suspend monitoring.
This patch allows to monitor battery health in-suspend state.
