MLK-18816-2 input/touch: do not clear touch interrupt when enable irq
On imx8mscale-evk baord, if I2C bus is configed pull-up, then once send
the i2c command to clear touch interrupt during the touch initialization,
touch will keep SDA line in low level, block the i2c bus. If config the
I2C bus pull-down, then this issue gone. Due to it is not reasonable to
set the I2c bus to pull-down for other i2c slave device, this patch work
as a workaround, just remove this i2c command, do not clear the touch
interrupt, test that touch can also work well after the initialization.
