ARM: 6072/1: oprofile: use perf-events framework as backend
There are currently two hardware performance monitoring subsystems in
the kernel for ARM: OProfile and perf-events. This creates the
following problems:
1.) Duplicate PMU accessor code. Inevitable code drift may lead to
bugs in one framework that are fixed in the other.
2.) Locking issues. OProfile doesn't reprogram hardware counters
between profiling runs if the events to be monitored have not been
changed. This means that other profiling frameworks cannot use the
counters if OProfile is in use.
3.) Due to differences in the two frameworks, it may not be possible to
compare the results obtained by OProfile with those obtained by perf.
This patch removes the OProfile PMU driver code and replaces it with
calls to perf, therefore solving the issues mentioned above.
The only userspace-visible change is the lack of SCU counter support
for 11MPCore. This is currently unsupported by OProfile userspace tools anyway and therefore shouldn't cause any problems.

This patch replaces the name string for a PMU with an enum, which holds
a unique ID for the PMU being represented. This ID can be used to index
an array of names within perf, so no functionality is lost. The presence
of the ID field, allows other kernel subsystems [currently oprofile] to
use their own mappings for the PMU name.

ARM: 6064/1: pmu: register IRQs at runtime
The current PMU infrastructure for ARM requires that the IRQs for the PMU
device are fixed at compile time and are selected based on the ARCH_ or MACH_ flags. This has the disadvantage of tying the Kernel down to a
particular board as far as profiling is concerned.
This patch replaces the compile-time IRQ registration with a runtime mechanism which allows the IRQs to be registered with the framework as
a platform_device.
A further advantage of this change is that there is scope for registering
different types of performance counters in the future by changing the id
of the platform_device and attaching different resources to it.

Thecus N2100 has a jumper (J3/J4) to select whether the XINT1 interrupt
line is connected to the second UHCI controller (position J3) or to
the serial port UART (position J4). Currently, the kernel is hardcoded
to assume the J3 position, and the serial port is always being used in
polling mode.
The patch adds the IRQ autodetection flag for the serial port interrupt,
and also marks it as shared (as the driver for the second UHCI controller
will request the interrupt in any case). Now, when the jumper is set to
the J4 position, the serial port will have an interrupt line, resulting
in less CPU overhead and faster throughput.
