Both H_IS and H_IE needs to be set to receive H_RDY
interrupt

1. Assert H_IS to clear the interrupts during hw reset
and use mei_me_reg_write instead of mei_hcsr_set as the later
strips down the H_IS

2. fix interrupt disablement embarrassing typo
  hcsr |= ~H_IE -> hcsr &= ~H_IE;
this will remove the unwanted interrupt on power down

3. remove useless debug print outs

netlink_send is supposed to send just the cn_msg+hv_kvp_msg via netlink.
Currently it sets an incorrect iovec size, as reported by valgrind.

In the case of registering with the kernel the allocated buffer is large
enough to hold nlmsghdr+cn_msg+hv_kvp_msg, no overrun happens. In the
case of responding to the kernel the cn_msg is located in the middle of
recv_buffer, after the nlmsghdr. Currently the code in netlink_send adds
also the size of nlmsghdr to the payload. But nlmsghdr is a separate
iovec. This leads to an (harmless) out-of-bounds access when the kernel
processes the iovec. Correct the iovec size of the cn_msg to be just
cn_msg + its payload.

Update extcon for 3.12

This patchset add new file for OF helper API and modify small fix of extcon-palmas
driver. Also, extcon core dirver use power_efficient_wq instead of system_wq.

Detailed description for patchset:
1. Add new file for OF helper API
- Add OF(OpenFirmware) Helper API which is of_extcon_get_extcon_device().
  This helper API get the extcon device name on extcon consumer device.
- Add usase case about OF helper API of extcon in dwc3-omap.c. dwc3-omap driver
  use extcon subsystem to detect the state of USB/USB-Host cable so dwc3-omap
  call of_extcon_get_extcon_device() to need extcon device name.

2. Modify extcon-palmas.c driver
- Provide option to select whether interrupt is used or not
- Support suspend/resume for palmas driver
- Update palmas interrupt register to detect ID pin
- Code clean to remove unused data
- Rename filename for device tree binding (extcon-twl.txt -> extcon-palmas.txt)

3. Use power_effcient_wq on extcon core driver/extcon-arizona instead of system_wq
- extcon core driver(extcon-gpio.c/extcon-adc-jack.c) use power_effcient_wq
instead of system_wq.

When integrating driver with Tegra platform, it is found that

further removal and re-insert does not detect the ID pin.

occurred.

previous status, set the cable state.

of_extcon_get_extcon_dev() uses dev_name for getting the reference
to the extcon device. If the extcon driver assigns a different
name other than dev_name, of_extcon_get_extcon_dev() wouldn't
be able to find the reference to the extcon device. Since the
client drivers of extcon-palmas would be using
of_extcon_get_extcon_dev(), removed assigning edev.name

Initially it was supposed to show the "Linux Integration Services"
version, now it is not in sync anymore with the out-of-tree drivers
available from the MSFT website.

The only place where a version string is still required is the KVP
command "IntegrationServicesVersion" which is handled by
