This patch adds block GPIO API support to the MAX730x driver.
Due to hardware constraints in this chip, simultaneous access to GPIO lines can
only be done in groups of 8: GPIOs 0-7, 8-15, 16-23, 24-27. However, setting
and clearing will be done at once.

This patch removes the call to irq_alloc_descs() which always returns an error
since the descriptors are always preallocated already.

There is a race condition between creating a gpio or gpiochip device and adding
default attribues. This patch fixes this by defining the default attributes as
dev_attrs of the class. For this, it was necessary to create a separate
gpiochip_class besides gpio_class.

This patch adds block GPIO API support to the MAX730x driver.
Due to hardware constraints in this chip, simultaneous access to GPIO lines can
only be done in groups of 8: GPIOs 0-7, 8-15, 16-23, 24-27. However, setting
and clearing will be done at once.

This patch enables support for i.MX53 in addition to i.MX25 by providing a
dummy clock on i.MX53 since this one doesn't have a separate clock for internal
RTC but the driver requests one.
