[PATCH] gpio: xgs-iproc: Fix crash when driver is built as a module

[Jon Hunter <jonathanh@nvidia.com>]

Commit 6a41b6c5fc20 ("gpio: Add xgs-iproc driver") introduced a new
GPIO driver for the Broadcom GPIO controller. When this driver is built
as a module the following warning is observed because the
bcm_iproc_gpio_of_match structure is defined with the __initconst
attribute ...

 MODPOST vmlinux.o
 WARNING: vmlinux.o(.data+0x834d0): Section mismatch in reference from
 the variable bcm_iproc_gpio_driver to the variable
 .init.rodata:bcm_iproc_gpio_of_match
 The variable bcm_iproc_gpio_driver references
 the variable __initconst bcm_iproc_gpio_of_match

This then causes a translation fault on boot which and results in a
system crash. Fix this by dropping the __initconst attribute from the
bcm_iproc_gpio_of_match structure.
