Hello,

In the Aspeed SoCs we have some reset registers spread out in various parts of
the soc: in the system controller IP, as well as other peripherals. I need to be
able to deassert those resets before other drivers work.

In writing a driver to do this I realised it was very generic. So instead I've
sent a generic driver that can be used by the device tree to clear reset lines
described by single bits in a register.

Let me know what you think of the idea. I've tested this driver on our SoC to
release the UART reset.
