gpio: aspeed: fix ast2600 bank properties

[ Upstream commit 560b6ac ]

GPIO_T is mapped to the most significant byte of input/output mask, and
the byte in "output" mask should be 0 because GPIO_T is input only. All
the other bits need to be 1 because GPIO_Q/R/S support both input and
output modes.
