Add the 'gpiomux' api, which addresses the following shortcomings
of existing tlmm api:

- gpio power-collapse, which is managed by a peripheral processor on
  other targets, must be managed by the application processor on the 8x60.
- The enable/disable flag of the legacy gpio_tlmm_config api
  is not applicable on the 8x60, and causes confusion.
- The gpio 'direction' bits are meaningless for all func_sel
  configurations except for generic-gpio mode (func_sel 0), in which
  case the gpio_direction_* functions should be used.  Having these
  bits in the tlmm api leads to confusion and misuse of the gpiolib
  api, and they have been removed in gpiomux.
- The functional api of the legacy system ran contrary to the typical
  use-case, which is a single massive configuration at boot.  Rather
  than forcing hundreds of 'config' function calls, the new api
  allows data to be configured with a single table.

gpiomux_get and gpiomux_put are meant to be called automatically
when gpio_request and gpio_free are called, giving automatic
gpiomux/tlmm control to those drivers/lines with simple
power profiles - in the simplest cases, an entry in the gpiomux table
and the correct usage of gpiolib is all that is required to get proper
gpio power control.

Masking in the ack callback fails to work with handle_percpu_irq and handle_edge_irq.
The interrupt stays disabled after the first invocation since percpu and edge irq do
not unmask an interrupt after handling it. For handle_level_irq masking in the ack
is redundant because ack is always called after mask in the mask_ack function.

Masking in the ack function is required only when __do_IRQ was used instead of flow
handlers, but using __do_IRQ has been deprecated.

Remove the masking of interrupt from the ack callback.

"param->u.wpa_associate.wpa_ie_len" comes from the user.  We should
check it so that the copy_from_user() doesn't overflow the buffer.

Also further down in the function, we assume that if
"param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is
initialized.  To make that work, I changed the test here to say that if
"wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return
-EINVAL.

Oddly, we only use the first element of the abyWPAIE[] array.  So I
suspect there may be some other issues in this function.

This reverts commit 96d592ed.

The netfilter hook seems to be misused and may leak skbs in situations
when NF_HOOK returns NF_STOLEN. It may not filter everything as
expected. Also the ethernet bridge tables are not yet capable to
understand batman-adv packet correctly.

It was only added for testing purposes and can be removed again.

Commit 461c3177(into 2.6.36-v3)
is put forward to power down phy if no usb cable is connected,
but does introduce the two issues below:

1), phy is not into work state if usb cable is connected
with PC during poweron, so musb device mode is not usable
in such case, follows the reasons:
	-twl4030_phy_resume is not called, so
		regulators are not enabled
		i2c access are not enabled
		usb mode not configurated

2), The kernel warings[1] of regulators 'unbalanced disables'
is caused if poweron without usb cable connected
with PC or b-device.

This patch fixes the two issues above:
	-power down phy only if no usb cable is connected with PC
and b-device
	-do phy initialization(via __twl4030_phy_resume) if usb cable
is connected with PC(vbus event) or another b-device(ID event) in
twl4030_usb_probe.

This patch also doesn't put VUSB3V1 LDO into active mode in
twl4030_usb_ldo_init until VBUS/ID change detected, so we can
save more power consumption than before.

This patch is verified OK on Beagle board either connected with
usb cable or not when poweron.
