drivers/i2c/rt5645: Add RT5645 amp driver

RT5663 is very old and it was used the hard code like RT53 or 10EC5663,
which is the different series from RT5645/5650, it may caused some
ambiguity. Because I2C generic driver dose not support dsd gpio
setting, we declared the new rt5645 series driver for expansion.

Add RT5645 AMP support. The kernel driver of 5650 is written
in rt5645.c. Add acpi name cbj-sleeve-gpios for power gate GPIO.
ALC5650 DataSheet Rev 0.93

Hide the device because of Microsoft Windows.

BUG=None
TEST=verified in anraggar and probe device rt5650 succeed
