atheros: simplify AR2315 misc IRQ (un)masking

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.

atheros: simplify gpiolib realization

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

atheros: update macroses names

Use AR2315_ prefix for macroses specific to AR2315/AR2316/AR2317 chips,
use AR5312_ prefix for macroses specific to AR5312/AR2312/AR2313 chips,
and use AR231X_ prefix for common macroses.

This patch should not cause any functional changes, only make clear
which macros is common and which macros is specific.
