Alex Bee e9006f81fa mfd: rk8xx: Add RK816 support 
This integrates RK816 support in the this existing rk8xx mfd driver.

This version has unaligned interrupt registers, which requires to define a
separate get_irq_reg callback for the regmap. Apart from that the
integration is straightforward and the existing structures can be used as
is. The initialization sequence has been taken from vendor kernel.
