pinctrl: imx5: fix GPIO_8 pad CAN1_RXCAN configuration

3 is an invalid value for the CAN1_IPP_IND_CANRX_SELECT_INPUT
register. Set it to 2, which correctly selects the GPIO_8 pad.

drivers/pinctrl/pinctrl-at91.c: convert kfree to devm_kfree

The function at91_dt_node_to_map is ultimately called by the function
pinctrl_get, which is an exported function.  Since it is possible that this
function is not called from within a probe function, for safety, the kfree
is converted to a devm_kfree, to both free the data and remove it from the
device in a failure situation.

pinctrl: sirf: add missing DT-binding document

While sending email to Linus for reviewing:
"pinctrl: sirf: add DT-binding pinmux mapping support"
https://patchwork.kernel.org/patch/1364361/

i have included the devicetree/bindings/pinctrl/pinctrl-sirf.txt

But while sending pull request with commit 056876f6c73406c,
i missed the document.

this patch takes the document back.

pinctrl: sirf: enable GPIO pullup/down configuration from dts

commit 7bec207427c2efb794 remove sirfsoc_gpio_set_pull function,
this patches takes the feature back by adding sirf,pullups and
sirf,pulldowns prop in dts, and the driver will set the GPIO
pull according to the dts.

pinctrl: nomadik: return if prcm_base is NULL

This patch adds a check for npct->prcm_base to make sure that the
address is not NULL before using it, as the driver was made capable of
loading even without a proper memory resource in:

f1671bf pinctrl/nomadik: make independent of prcmu driver

Also, refuses to probe without prcm_base on anything else than nomadik.

This solves the following crash, introduced during the merge window when
booting on U8500 with device tree:

 "A first round of pinctrl fixes for v3.8:
   - i.MX5 register configuration
   - Swap a kfree to devm_kfree() to avoid memory corruption in the at91
     driver
   - Add the missing device tree binding doc for the SIRF pin controller
   - Enable the SIRF GPIO pull up/down configuration from the device
     tree, it was previously retired from the hard-coded approach.
   - NULL check for the prcm_base in the Nomadik pin controller.
   - Provide the prcm_base from the device tree in the DT boot path for
     the Nomadik pin controller."
