gpio: tps65219: Fix GPIO input value reads

Browse source

TPS65219_MFP_GPIO_STATUS_MASK is already BIT(4). Passing it to BIT()
again tests bit 16, which cannot be set in the 8-bit MFP_CTRL register,
so GPIO0 is always reported low when configured as an input.

Test the register value with the mask directly.
