When building pinctrl-ssbi-gpio and pinctrl-ssbi-mpp for ARM64, we get
a compile warning about invalid types:

drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c: In function 'pm8xxx_gpio_probe':
drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c:675:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/pinctrl/qcom/pinctrl-ssbi-mpp.c: In function 'pm8xxx_mpp_probe':
drivers/pinctrl/qcom/pinctrl-ssbi-mpp.c:766:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

This changes the code so we cast the pointer to 'unsigned long', which
is the right thing to do here.

The DEBUG_FS=n #defines for the dbg_show functions were missed when
renaming the driver from msm_ to pm8xxx_, causing it to break the build
when DEBUG_FS isn't enabled:

  CC [M]  drivers/pinctrl/qcom/pinctrl-ssbi-gpio.o
drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c:597:14: error: ‘pm8xxx_gpio_dbg_show’ undeclared here (not in a function)
  .dbg_show = pm8xxx_gpio_dbg_show,

Fix this by renaming them correctly.

Since commit 323de9ef ("pinctrl: make pinctrl_register() return proper
error code"), pinctrl_register returns an error code rather than NULL on
failure.  Update some drivers that were introduced more recently.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,e1,e2;
@@

e = pinctrl_register(...)
... when != e = e1
if (
-   e == NULL
+   IS_ERR(e)
   ) {
     ...
     return
-      e2
+      PTR_ERR(e)
     ;
     }

This introduces pinctrl drivers for gpio and mpp blocks found in family A
PMICs.
