Fix the section mismatch warning
WARNING: vmlinux.o(.text+0x2b2788): Section mismatch in reference from the function mxc_gpio_probe() to the function .init.text:mxc_gpio_init_gc()
The function mxc_gpio_probe() references
the function __init mxc_gpio_init_gc().
This is often because mxc_gpio_probe lacks a __init
annotation or the annotation of mxc_gpio_init_gc is wrong.

Currently in the FSL platform all GPIO interrupts in a bank are muxed
into two GPIO lines to the GPC interrupt controller. In each GPIO bank
GPIOs 0-15 are OR'ed into one GPC interrupt controller interrupt and 16-31
are OR'ed into another. With the current code, if any of the 0-15 or
16-31 interrupts are marked as wakeup capable, all interrupts belonging
to that sub-bank (either 0-15 or 16-31) will wake up the device. This is
because interrupts are only being masked at the interrupt controller
and not at the GPIO controller.
This patch allows masking of GPIO interrupts at the GPIO controller during
suspend if they have not been labeled wakeup capable. This patch uses
preexisting IRQCHIP_MASK_ON_SUSPEND flag while initializing the GPIO
interrupts to get the desired behavior.

alloc_orinocodev() would allocate the wiphy entry, but it would only get
registered much later in orinoco_init(). If something failed in the init
process inbetween the call to alloc_orinocodev() and the completion
of orinoco_init(), the drivers would end up calling wiphy_unregister()
with a NULL pointer causing beautiful OOPS fireworks.

In this driver, two variables are masked by one quantity, and then tested
against a second number with more bits that the mask. Accordingly, the
test always fails. To minimize the possibility of such typos, a symbolic
definition of the mask is created and used.
The separate load and mask operations are also combined into a single
statement.

Commit e996db6983 (rtlwifi: rtl8192c: Add init codes for "fw_version"
and "fw_subversion") added initialization for fw_version, but failed to
note that the variable in the firmware header is little-endian. The
following Sparse warning results:
CHECK drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types)

drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: got restricted __le16 [usertype] version
When fixing this problem, I noticed that several of the drivers contain
nearly identical copies of the firmware header struct, and that only the one
used in rtl8192c{e,u} had correct endian notation. The struct has been
moved into a common header, and the other drivers will be fixed in
subsequant patches.
