On palawan target, TP avdd was loaded on L22B which limited the voltage
from 2700mv to 3400mv and initialized to 2700mv. From the touch side,
the typical voltage is 2.8v~3.2v, and our existing FW was tuned based on AVDD 3.2V.

Increasing the load current for touch IC to 30mA from 14mA to avoid
the regulator from going into LPM, as some touch panels are drawing
more power.

disable_irq ensures existing instances of the IRQ handler have
completed before returning which may create a deadlock if the handler
doesn't find the resource.

It is found there might be some i2c NACK error after
power on and reset operation, from goodix datasheet
it is required to wait 100ms after reset operation
before I2C communication, so put a 100ms sleep after
reset.

Add more checks in brl_send_config to ensure the config
data sent by user is valid. Also add more parameter
checks in brl_read_config function.

In power_on function, it already contain reset operation,
so no need to do reset again after power_on, to save time
when do resume operation.

Currently when display off, host will send command to make touch
IC enter sleep mode, but from power team's requirement, touch IC
should be totally power off when display off.
