ARM: integrator: deactivate timer0 on the Integrator/CP

This fixes a long-standing Integrator/CP regression from
commit 870e2928cf3368ca9b06bc925d0027b0a56bcd8e
"ARM: integrator-cp: convert use CLKSRC_OF for timer init"

When this code was introduced, the both aliases pointing the
system to use timer1 as primary (clocksource) and timer2
as secondary (clockevent) was ignored, and the system would
simply use the first two timers found as clocksource and
clockevent.

However this made the system timeline accelerate by a
factor x25, as it turns out that the way the clocking
actually works (totally undocumented and found after some
trial-and-error) is that timer0 runs @ 25MHz and timer1
and timer2 runs @ 1MHz. Presumably this divider setting
is a boot-on default and configurable albeit the way to
configure it is not documented.

So as a quick fix to the problem, let's mark timer0 as
disabled, so the code will chose timer1 and timer2 as it
used to.

This also deletes the two aliases for the primary and
secondary timer as they have been superceded by the
auto-selection

mvebu.

It is hoped that he will continue this work, and also assist the current
mvebu maintainers with patch wrangling and pull request submissions.

nfsd regression since delayed fput()

Background: nfsd v[23] had throughput regression since delayed fput
went in; every read or write ends up doing fput() and we get a pair
of extra context switches out of that (plus quite a bit of work
in queue_work itselfi, apparently).  Use of schedule_delayed_work()
gives it a chance to accumulate a bit before we do __fput() on all
of them.  I'm not too happy about that solution, but... on at least
one real-world setup it reverts about 10% throughput loss we got from
switch to delayed fput.

 "There's really only one bugfix in this branch, which is a fix for
  timers on the integrator platform.  Since Linus Walleij is
  resurrecting support for the platform it seems valuable to get the fix
  into 3.12 even though the regression has been around a while.

  The rest are a handful of maintainers updates.  If you prefer to hold
  those until 3.13 then just merge the first patch on the branch which
  is the fix"

  ARM: integrator: deactivate timer0 on the Integrator/CP
seq_file: always update file->f_pos in seq_lseek()

This issue was first pointed out by Jiaxing Wang several months ago, but no
further comments:
https://lkml.org/lkml/2013/6/29/41

As we know pread() does not change f_pos, so after pread(), file->f_pos
and m->read_pos become different. And seq_lseek() does not update file->f_pos
if offset equals to m->read_pos, so after pread() and seq_lseek()(lseek to
m->read_pos), then a subsequent read may read from a wrong position, the
following program produces the problem:

    char str1[32] = { 0 };
    char str2[32] = { 0 };
    int poffset = 10;
    int count = 20;

    /*open any seq file*/
    int fd = open("/proc/modules", O_RDONLY);

    pread(fd, str1, count, poffset);
    printf("pread:%s\n", str1);

    /*seek to where m->read_pos is*/
    lseek(fd, poffset+count, SEEK_SET);

    /*supposed to read from poffset+count, but this read from position 0*/
    read(fd, str2, count);
    printf("read:%s\n", str2);

out put:
pread:
 ck_netbios_ns 12665
read:
 nf_conntrack_netbios

/proc/modules:
nf_conntrack_netbios_ns 12665 0 - Live 0xffffffffa038b000
nf_conntrack_broadcast 12589 1 nf_conntrack_netbios_ns, Live 0xffffffffa0386000

So we always update file->f_pos to offset in seq_lseek() to fix this issue.
