gpio_chip and reg_base to avoid global gpio_reg_base.

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

When no flags are given, the native endianness is used to access
the MMIO registers, and the pin2mask() call can simply be
converted to a BIT() call, as per the default pin2mask()
implementation in gpio-mmio.c.

Remove unneeded error handling on the result of a call
to platform_get_resource() when the value is passed to
devm_ioremap_resource().

The Kconfig for this file is:
drivers/gpio/Kconfig:config GPIO_LOONGSON1
drivers/gpio/Kconfig: tristate "Loongson1 GPIO support"
...but however it does not include module.h -- it in turn gets it from
another header (gpio/driver.h) and we'd like to replace that with a
forward delcaration of "struct module;" but if we do, this file will
fail to compile.
So we fix this first to avoid putting build failures into the bisect
commit history.
