hw: aspeed_gpio: Fix pin I/O type declarations

Some of the pin declarations in the Aspeed GPIO module were incorrect,
probably because of confusion over which bits in the input and output
uint32_t's correspond to which groups in the label array. Since the
uint32_t literals are in big endian, it's sort of the opposite of what
would be intuitive. The least significant bit in ast2500_set_props[6]
corresponds to GPIOY0, not GPIOAB7.

GPIOxx indicates input and output capabilities, GPIxx indicates only
input, GPOxx indicates only output.

AST2500:
- Previously had GPIW0..GPIW7 and GPIX0..GPIX7, that's correct.
- Previously had GPIOY0..GPIOY3, should have been GPIOY0..GPIOY7.
- Previously had GPIOAB0..GPIOAB3 and GPIAB4..GPIAB7, should only have
  been GPIOAB0..GPIOAB3.

AST2600:
- GPIOT0..GPIOT7 should have been GPIT0..GPIT7.
- GPIOU0..GPIOU7 should have been GPIU0..GPIU7.
- GPIW0..GPIW7 should have been GPIOW0..GPIOW7.
- GPIOY0..GPIOY7 and GPIOZ0...GPIOZ7 were disabled.
