It fixes the issue in gpio-generic that commit fb14921 (gpio/mxc: add
missing initialization of basic_mmio_gpio shadow variables) manged to
fix in gpio-mxc driver, so that other platform specific drivers do not
suffer from the same problem over and over again.
Changes since v1:
* Turn the last parameter of bgpio_init() "bool big_endian" into
"unsigned long flags" and give those really quirky hardwares a
chance to tell that reg_set and reg_dir are unreadable.

Where appropriate factor out some boilerplate code for platform device
registration into module_platform_driver. Drivers that don't use the
standard module_init initcall haven't been converted.

Building a kernel with hotplug disabled results in a link failure:
`bgpio_remove' referenced in section `___ksymtab_gpl+bgpio_remove' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
This is because of bgpio_remove() is exported. It is illegal to export
symbols which are discarded either at link time or as part of an
init/exit section.
Fix this by dropping the __devexit attributation from bgpio_remove().
Also drop the __devinit attributation from bgpio_init().

Sort the gpio makefile and enforce the naming convention gpio-*.c for
gpio drivers.
v2: cleaned up filenames in Kconfig and comment blocks
