gpio: tc35894: fix up tc35894 interrupt configuration
The offset of regmap is incorrect, j * 8 is move to the
wrong register.
for example:
asume i = 0, j = 1. we want to set KPY5 as interrupt
falling edge mode, regmap[0][1] should be TC3589x_GPIOIBE1 0xcd
but, regmap[i] + j * 8 = TC3589x_GPIOIBE0 + 8 ,point to 0xd4,
this is TC3589x_GPIOIE2 not TC3589x_GPIOIBE1.
Fixes: d88b25be3584 ("gpio: Add TC35892 GPIO driver")
