gpio: tc35894: fix up tc35894 interrupt configuration
commit214b0e1ad0
upstream. 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.
