Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().

Most conversions are straight-forward.  Ones worth mentioning are,

* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
  use mod_delayed_work() and cancel loop in
  edac_mc_reset_delay_period() is dropped.

* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
  watchdog is active or not.  @fan_watchdog_active and related code
  dropped.

* drivers/power/charger-manager.c: Seemingly a lot of
  delayed_work_pending() abuse going on here.
  [delayed_]work_pending() are unsynchronized and racy when used like
  this.  I converted one instance in fullbatt_handler().  Please
  conver the rest so that it invokes workqueue APIs for the intended
  target state rather than trying to game work item pending state
  transitions.  e.g. if timer should be modified - call
  mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().

* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
  simplified.  Note that round_jiffies() calls in this function are
  meaningless.  round_jiffies() work on absolute jiffies not delta
  delay used by delayed_work.

v2: Tomi pointed out that __cancel_delayed_work() users can't be
    safely converted to mod_delayed_work().  They could be calling it
    from irq context and if that happens while delayed_work_timer_fn()
    is running, it could deadlock.  __cancel_delayed_work() users are
    dropped.

wait_for_completion_interruptible_timeout() may return negative value.
In this case, checking if (t > 0)  will return true if t is unsigned.

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

mfd_get_cell returns a const, so change the jz4740 clients to store
a const mfd cell.  This silences type mismatch warnings.

No need to explicitly set the cell's platform_data/data_size.

Modify clients to use mfd_get_cell helper function instead of
accessing platform_data directly.

During test-build (with disabled 'depends on') I found that
jz4740-battery driver lacks linux/io.h, which makes build break
like this (on x86):

  CC [M]  drivers/power/isp1704_charger.o
jz4740-battery.c: In function 'jz_battery_read_voltage':
jz4740-battery.c:84: error: implicit declaration of function 'readw’
jz4740-battery.c: In function 'jz_battery_probe':
jz4740-battery.c:284: error: implicit declaration of function 'ioremap_nocache’
jz4740-battery.c:285: warning: assignment makes pointer from integer without a cast
jz4740-battery.c:372: error: implicit declaration of function 'iounmap'
make[2]: *** [drivers/power/jz4740-battery.o] Error 1

This patch fixes the issues, and thus makes it easier to build-test
the driver for me.

Currently platform_data is dereferenced without checking whether it
is actually set, which can lead to kernel crashes.
This patch adds a check which will abort the drivers probe function
gracefully if no platform_data is supplied.

We can not handle more then one ADC request at a time to the battery.
The patch adds a mutex around the ADC read code to ensure this.
