Each SoCs generation has own independent gpiolib realization, so we
have no reason to keep these realizations in semiuniversal form.
Following modifications are made:
* Remove valid_mask field
* Remove ar231x_gpio_chip structure
* Rename AR2315_GPIO_CR to AR2315_GPIO_DIR
* Fix count of AR5312 GPIOs
* Simplify gpio_chip methods realization

Currently AR5312 misc IRQ numbers are used for AR2315+ chips, what cause
us to use switch-case to map IRQ number to ISR bit. Introduce AR2315
specific misc IRQs set and simplify interrupt (un)mask operation.

and add IRQ chips names.

We should not detect actual flash size during board initialization to
find board config at the end of the flash, just use large enough mapping
size (currently 128 mbit). If mapping size is larger than the actual
flash size, than flash will simply be mapped multiple times. This change
simplifies code by removing duplication and saves about 200 bytes of
uncompressed kernel :)
Tested with Ubnt LS2 board equipped with STM 25p32v6p NOR flash (32 mbit).
