This patch frees stmpe driver from tension of freeing resources.
devm_* derivatives of multiple routines are used while allocating resources,
which would be freed automatically by kernel.

At every boot of an (outdated) laptop lpc_ich prints an error:
    lpc_ich 0000:00:1f.0: I/O space for GPIO uninitialized

But if one looks at lpc_ich's probe function one notices that the code
only cares if both lpc_ich_init_wdt() and lpc_ich_init_gpio() fail to
add any cells. So stop treating the failure to add a single cell as an
error. Those messages can be printed at notice level. And then only warn
if no cells were added.

The older southbridges supported by the lpc_ich driver do not
provide memory-mapped space of the root complex. The driver
correctly avoids computing the iomem address in this case, yet
submits a zeroed resource request anyway (via mfd_add_devices()).

Remove the iomem resource from the resource array submitted to the
mfd core for the older southbridges.

control the Charging indicator LED on the twl6030 PMIC.
The new set of drivers are going to provide support for both PWMs and PWM
driven LED outputs on TWL4030 and TWL6030 PMICs.
The twl-pwm driver will handle the PWMs (2 instance) while the twl-pwmled

For Realtek card reader, internal regsiter SD_CFG2 should be configured
before transferring data.
The default value of SD_CFG2 is proper for writing data. But for reading
sequence, the timing is not good enough. So in some extreme circumstance,
card reader may sample the response data from the card as good even if
the data is wrong. And this will cause the bad consequence.
In the prior version, the value of this register has been calculated,
but forgotten to write back to the internal register.

A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.

Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:

* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.
